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

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...).

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.
