Product Texts
KURARITY is non-crystalline block copolymer and does not have melting point.
All the KURARITY grades show similar low temperature properties which result from Tg of poly (n-butyl acrylate) or poly (n-butyl acrylate/2-ethylhexyl acrylate) and heat resistance from Tg of PMMA.
LA series : n-butyl acrylate based block copolymers.
Suitable Applications: For Molding, Compound, Additives.
