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

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.
