Marketingon Apr 5, PM. Generally, these two materials have more similarities than differences. Both materials have the capability of being shaped into tall glasses commonly used in restaurants for water, fountain drink, and iced tea service.
The differences in durability, clarity, and handling vary between these two materials and will have different impacts on your operation depending on what your needs are.
The difference between these two materials yields different kinds of durability, but the design of the tumbler can also have an affect on durability. That's why buying your plastic tumblers from reputable manufacturers who are experts in foodservice plastic is important. They have trained design engineers who work to minimize weak points in product designs, improving the overall performance of your tumbler.
If that's the case, then SAN tumblers are your best choice between the two materials. However, if you prefer to have a bit more clarity in your plastic drinkware, PC tumblers are a good choice. Once you find the right fit, be sure to follow the recommended care and maintenance to get the longest service life possible out of your purchase, regardless of the plastic material you choose.

Connect With Us. Browse Our Products.One of our most popular posts is the one about the numbers on plasticswhere I talk about which plastic is safe to use.
In that post, I mention that not all 7 plastics are toxic. But how do you know which 7 plastics are safe? Many sources, like Healthy Child Healthy World will tell you to avoid most 7 plastics. Number 7 seems to be the dumping ground for all other types of plastic.
So how do you know which 7 plastics should be avoided? PLA plastics are bio plastics, made from polylactic acid, from starchy renewable resources like corn, and tapioca. Packaging will confirm that this 7 plastic is a PLA plastic, and is safe to use.
Tritan is a tough, clear copolyester plastic. They also say that it has no estrogenic or androgenic activity. However, a quick search on the internet throws some doubt on this.
Styrene Acrylates Copolymer
Eastman Tritan were involved in a court case against a scientist who claimed that Tritan did contain estrogenic chemicals. Although Eastman Tritan won this case, sources report that their testing methods were faulty, and that research was at least partly funded by a chemical industry body. So far, it seems that some research appears to show that Tritan is a safe plastic, although this research may not be independent.
Err on the side of caution and use it with cold liquids only. And like any other plastic, never use it in the microwave.

Greenpeace commissioned a report on which types of plastics could be used to replace PVC in toys. One of those plastics are TPEs thermoplastic elastomers. TPEs are the name for a group of plastics, and some are safer than others. TPEs are a often a copolymer, which is a mixture of two or more kinds of plastics. However, some TPEs are very safe.
Reputable companies, like BabyBjorn, are constantly testing their materials and will provide you with safety certifications if you request them.
So is plastic number 7 BPA free? That depends on which 7 plastic it is! I have just bought a new Tupperware clear mates set. Now I see a, 7 other, written on the bottom of them.

SAN is available in a range of colours and can be tailoured for specific applications. A variety of grades are available for different applications, the material is typically injection moulded or extruded. ASA is an acrylate rubber modified styrene acrylonitrile copolymer with an acrylate rubber modifier included at the polymerisation stage. It is also used for the outer casings of thermally insulated jugs, for tableware, cutlery, coffee filters, jars and beakers as well as storage containers for all kinds of foods.
An additional application is in multi-trip tableware for the catering sector. The pleasing appearance especially when coloured and the ease of printing on SAN has allowed a number of applications in the bathroom toothbrushes and bathroom fittings and cosmetic packaging, SAN is also hard wearing and is used in the office and in industry for diverse applications, all types of outer covers, e.
Other applications include scales, battery housings, winding cores, writing and drawing equipment and cylindrical impellers for air-conditioners. It looks good and feels good — an important consideration in the bath where we surround ourselves with pleasing things. SAN accepts print very easily and affords diverse design possibilities. Moreover, SAN is resistant to chemicals. SAN is also suitable for bathroom fittings and toothbrushes for example.
At Home SAN is used because of its extraordinary transparency and brilliance when colored. It is resistant to fats and oils and to cleaning agents. What is more it is dishwasherproof. In short SAN is exceptional for its high suitability for use in the home. SAN is employed in transparent parts such as containers, mixing bowls and basins for kitchen utensils and fittings for refrigerators.
SAN is also used for the outer casings of thermally insulated jugs, for tableware, cutlery, coffee filters, jars and beakers as well as storage containers for all kinds of foods. Office and industry The plastics used in the office and in industrial applications must exhibit longwearing characteristics.
Strength and dimensional stability are required. It even possesses high resistance to acids and alkalis, e.

Join the BPF.Styrene acrylates copolymer is a chain of polymers consisting of styrene and acrylate which is added to cosmetics for color.
There is the potential for styrena acrylates copolymer to be contaminated with styrene, a possible carcinogen. Styrene acrylates copolymer may contain a small amount of residual styrene. Styrene is used predominately in the production of polystyrene plastics and resins. Styrene is also used as an intermediate in the composition of materials used for ion exchange resins and to produce copolymers. It is quickly broken down in the air, usually within days.
However, contamination with the possible carcinogen styrene is a concern. Our tests did not reveal detectable levels of styrene in fragranced products tested. Even in trace amounts it is concerning to have the presence of a carcinogen in products marketed to children and adults. Styrene acrylates copolymer itself has no evidence of adverse health effects, but our tests illustrate its potential contamination with styrene.
Not all products we tested with styrene acrylates copolymer had detectable levels of styrene; as a result, there is no simple way to know if a product contains residual styrene. Instead, it would require lab testing to determine if it is present in products, and at what levels. Styrene may also serve as a film-forming agent. Cancer: Styrene is a reasonably anticipated human carcinogen by the International Agency for Research on Cancer  and by the National Toxicology Program.
There is also some evidence for increased risk of cancer in the pancreas or esophagus among some styrene workers, but the evidence is weaker than that for lymphohematopoietic cancers.
Endocrine Disruption: The European Commission on Endocrine Disruption classifies styrene as a Category 1 endocrine disruptor, meaning evidence for endocrine disruption has been documented in humans and wildlife. Other effects: Short-term exposure to styrene in humans results in mucous membrane and eye irritation, and gastrointestinal effects. Long-term exposure to styrene in humans results in effects on the central nervous system CNSsuch as headache, fatigue, weakness, and depression, CSN dysfunction, hearing loss, and nerve damage.

Polymers11 11 Jingru Liu, Jiaxi Liu.Styrene acrylonitrile resin is a copolymer plastic consisting of styrene and acrylonitrile. It is also known as SAN. It is widely used in place of polystyrene owing to its greater thermal resistance.
The chains of the polymer show alternating repeat units of styrene and acrylonitrileand it is a copolymer. SAN is similar in use to polystyrene. Like polystyrene itself, it is optically transparent and brittle in mechanical behavior. It is structurally related to ABS plastic, where polybutadiene is copolymerised with SAN to give a much tougher material.
The rubber chains form separate phases which are micrometers in diameter. When the product is stressed, crazing from the particles helps to increase the strength of the polymer. The method of rubber toughening has been used to strengthen other polymers such as PMMA and nylon. Uses include food containers, water bottles, kitchenware, computer products, packaging material, battery cases and plastic optical fibers.
The acrylonitrile from SAN containers has been found to migrate to content in variable amounts. From Wikipedia, the free encyclopedia. CAS Number. Chemical formula.
