Acrylonitrile Styrene Acrylate (ASA) - ASA is produced by introducing a grafted acrylic ester elastomer during the copolymerization reaction between styrene and acrylonitrile. Acrylonitrile styrene acrylate material has great toughness and rigidity, good chemical resistance and thermal stability, outstanding resistance to weather, aging and yellowing, and high gloss.
Acrylonitrile styrene acrylate (ASA) was first introduced by BASF in about 1970 as Luran S. The intent was to create a material similar to ABS but with better weather resistance. Because of this attribute acrylonitrile styrene acrylate has been used heavily in the automotive industry, as well as several other outdoor applications.
High impact resistance
High heat resistance
Good impact resistance
●PMMA vs ASA
The advantages of ASA:
-Excellent chemical resistance
-Low density PMMA = 1.19, ASA = 1.07
-Wider spectrum (matte ~ glossy)
-Thermal stability is better
- Strong adhesion force with PVC
- Typical characteristics are Impact strength and Adhesive strength
Here are important index to measure the quality grade of all kinds of recycled material particles.
1.Surface finish: high quality recycled material is smooth and lubrication;
2.Transparency: usually, the material is lucid, and the quality is good;
3.Color uniformity and consistency;
4.Particle density is an important aspect to test the regeneration process: bad plasticization, loose particles;
5.Whether the recycled particles float and sink in the water to test the content of PP and PE particles.
About recycled materials, different recycled materials have different uses, because there is no unified standard, to fully meet the user's technical requirements shall prevail.
