The Universal Selection Source: Plastics & Elastomers

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.

Discover CET® Styrene Acrylic resin's key properties

What are the key properties of Styrene Acrylic resin?

CET® is a cost-effective transparent resin with superb surface aesthetic. Its mechanical attributes are suitable for everyday life applications. Impact-modified grades are also available to get superior mechanical properties, such as higher-impact resistance, when required.

Compared to other transparent resins, CET® is so much easier to process. It does not require pre-drying and it can be extruded or injection-molded at lower temperatures than PMMA, MABS and PC. Here is an overview of the CET® key properties:

Why choose CET® SMMA over other transparent thermoplastics?

CET® is a well-balanced resin offering performance in between styrene and acrylic thermoplastics. Here is a technical comparison of CET® resin versus PMMA and SAN.

Compared to polystyrene or SAN, CET® offers superior mechanical performance with much better surface aesthetic. Polystyrene often looks and feels cheap whereas CET® Styrene Acrylic resin does not. In addition, CET® offers gorgeous glossy surface comparable to PMMA or MABS. Read our case study dealing with the development of disposable razors made of CET® instead of polystyrene.

If you are using PMMA, polycarbonate, PET, MABS or any over-specified material, CET® resins is a less expensive alternative offering competitive aesthetic quality with much easier processing. CET® resins are very good in practical toughness (not abusive) and very good in everyday life conditions. The following case study will show you why CET® has been preferred over PMMA to develop a gorgeous ice-bucket for a luxury champagne producer.

Case Studies from SMMA - styrene-acrylic copolymer

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.
