WebAug 7, 2024 · Poly(butyl acrylate) (PBA) is a polymer with low glass transition temperature and high UV resistance . Polystyrene (PS) is a glassy, amorphous polymer with outstanding clarity, gloss, and processability. However, it suffers from inherent brittleness, limiting its use in application where deformation resistance is required. WebAnswer / Solution. The main difference between the Viton material and the Butyl material in a glove is that they are two different polymers. Therefore, they would protect from chemicals differently. When working with or being exposed to chemicals it is very important to know the breakthrough time with regard to the chemical and glove of choice.
WebProperties. Polyacylates are an important class of polymers that are soft, tough and rubbery. Their glass transition temperature is well below room temperature. They are known for their high transparency, good impact toughness and elasticity, and have fairly good heat resistance up to ca. 450 K under dry heat. They also have good weatherability ... http://www.bio-review.com/polystyrene-b-poly-2/
