CET® is a range of transparent styrene-acrylic copolymers (SMMA). These materials combine the aesthetic quality and mechanical properties of  acrylic resins while combining the cost efficiency of styrenics. CET® is an excellent cost-efficient alternative to PC/PMMA or PS/clear PP upgrade.

FAQ: find answers about CET® Styrene Acrylic copolymer

What are the main properties of CET® resin?

CET® is a rigid, transparent resin with an excellent clarity and high quality glossy surface. Its main advantage is its cost-competitiveness and specific gravity compared to PMMA, PC, MABS and also styrenic resins like SAN and PS. It resists to day to day chemical and physical conditions. In summary, CET® is a well-balanced and cost-effective transparent resin having an excellent aesthetic quality, competing with more expensive clear resins. Learn more about CET® key properties.

How much does CET® Styrene Acrylic copolymer cost?

CET® is cheaper than PMMA, PC, MABS and PET. Compared to polystyrene or SAN, the price range is almost equivalent, depending on the ordered volume and selected CET® grade.

Does CET® look cheap?

Not at all. On the contrary, CET® has been used for high-end applications and competes against PMMA and MABS. Styrenic resins like polystyrene have a cheap look 'n' feel, which is definitely not the case with CET® resins. Take a look at the following luxury champagne ice-bucket case study using CET®. You will find it overachieving in its aesthetic properties.

Will a part made of CET® polymer be drop-resistant?

It depends on the parts' design, its thickness and also if the CET® grade is reinforced or not. In general: Yes. CET® has shown in many cases to be drop-resistant.

It will also depend on the safety standards you may want to claim, like shatter-resistant or unbreakable, or if your are replacing another plastic part or a glass-made part. A double-walled tumbler manufacturer replaced its unbreakable PET grade for CET® SMMA resin and the tumblers are still passing their drop tests. You can read their full story here.

Is there any impact-modified grade available?

CET® is available in neat or impact modified grades. Impact modified grades offer excellent impact resistance (Notched Izod 530 J/m at 0.125 in / 3.175 mm). View the CET® portfolio to get a comprehensive overview of all available grades.

To what chemicals does CET® resist to?

CET® resists to soap, dishwashing liquids and household detergents. A tumbler manufacturer has selected CET® to replace PET and run dishwashing test. CET® passed the test, take a look at the whole case study and the results here.

For what type of applications is CET® suitable for?

CET® is suitable for transparent, cost-effective day to day applications like: drinking glasses and partyware, tableware, cosmetics package, medical devices, personal hygiene items, office supplies, toys, promotional items, disposable goods like razors, etc...

How does CET® performs compared PMMA, PC, MABS, PS and SAN?

On aesthetics, CET® styrene acrylic polymer gives similar surface quality than PMMA, MABS or PC. Polystyrene looks cheap and this is why CET® is an excellent cost-effective alternative with far better quality.

On a cost stand point, CET® is cheaper than PMMA, PC, MABS and PET and very competitive compared to PS and SAN.

CET® has also a good impact and scratch resistance. Impact modified grades are available with better impact resistance than neat grades. CET® has a lower impact resistance than PMMA, PC or PET, but it still delivers good resistance to day-to-day conditions (drops, shocks...).

Take a look to our case study gallery to learn more about PMMA, PC, PET or PS replacement with CET®.

What is the CET® processing temperature?

Here are the temperatures used for CET® for injection-molding:
Feeding zone: 160-180°C, Initial zone: 170-190°C, Medium zone: 180-200°C, Nozzle zone: 200-220°C, Maximum temperature profile: 250°C

Find more information in CET® technical datasheets.

Do we need to dry the CET® pellets prior to the processing?

No. Unlike PMMA, PC, PS or MABS, CET® does not require any pre-drying before being processed.

Case Studies from SMMA - styrene-acrylic copolymer

Single-use Medical Syringes benefit from Crystal-Clear Clarity and Crack Resistance of CET® SMMA

Because safety and prevention are at the heart of medical applications, especially when in contact with the human body, the industry continues to move toward disposable products to avoid any contamination. These safe disposal products include single-use medical syringes. 

Manufactures of single-use medical syringes need tough polymers that can withstand high temperatures, sterilization, gamma radiation. They also value a material that offers excellent clarity for aesthetic appeal and that can be dropped with no concern of breakage. The right material solution also needs to be available at a reasonable cost that is acceptable for a disposable part. Currently, transparent materials like PMMA, SAN or PC cannot provide this combination of benefits at a reasonable cost.

Dowload this case study to learn more about a solution that is an ideal combination between processing ease, typical to styrene polymers, and the crystal clarity of straight acrylic!


Design gorgeous yet cost-effective promotional items like champagne ice bucket thanks to CET® resin

Top-brand owners look permanently for promotional campaigns to keep their position in the consumers’ preference while solidifying their presence as high quality standards.

A prestigious champagne producer decided to offer a luxury logo-printed ice bucket to its customers who purchased several bottle packages. He needed a cost-effective yet beautiful transparent resin as the ice bucket would represent the brand and the champagne’s quality and reputation.

They evaluated CET® SMMA resins which delivered a more interesting cost/aesthetic balance than PMMA for instance. Download the case study to get the full story.


They developed cost-effective double-walled tumblers by replacing PET with SMMA

A residential glass producer was using PET-G to inject double-walled tumblers. Thanks to the excellent impact resistance of PET, the producer claimed his glasses unbreakable but the glasses were too expensive.

He wanted to find a less expensive resin, with glossy surface and good impact resistance to drops while being also resistant to dish washings. He have found it in SMMA.


They have chosen CET® SMMA for glossy transparent disposable razors

Resirene CET® SMMA resin has been selected by a key company for brand new disposable razors. Learn more about the unique combination of good mechanical properties, glossy/transparent aesthetic and attractive cost-effectiveness of CET® through this case study.
