Overview
The acrylate processing additive K278P produced by
JOYSUN is suitable for the production and
processing of PVC products.
Application
K278P is a PVC foam regulator with medium melt
strength, which can significantly promote PVC
melting at low temperature, effectively lower the
plasticizing temperature and shorten the
plasticizing time. In addition, it can also
strengthen the cohesion and homogeneity of PVC
melt, and give PVC polymer higher melt strength,
elongation and elasticity while broadening the
processing temperature range, reduce the pulsation
and instability of melt, and promote the surface
brightness and smoothness. The product has good
dispersion and
processing fluidity in PVC, which is suitable for
the production and processing of all kinds of PVC
foamed building materials and profiles, effectively
improving the production efficiency. Uniform the
cell structure of PVC foaming products by improving
the melt strength, used with the blowing agent can
excellently minimize the product density. Suitable
for process with slow plasticizing speed.
