MITSUBISHI RAYON METABLEN

METABLEN P type is an acrylic processing aid that offers significant benefits to processors of PVC, ABS, polycarbonate and other thermoplastics. METABLEN P type greatly improves the melt elasticity of thermoplastics and promotes fusion of PVC with addition of low use levels. These products are designed to offer maximum dispersability in much kind of thermoplastics. METABLEN P type is possible to correspond wide range of molecular weight.

METABLEN P type is high molecular weight and excellent compatibility with thermoplastic resin. Molecules of METABLEN P type easily entangle with molecules of thermoplastic resin, when kneaded under heating, and it forms physical bonds. -The physical bonds correspond to vulcanization of rubber-. Thus, the molten thermoplastic resin attains rubber-like elasticity, which contributes to better processability of compounds.
