Production Description
Polypropylene random copolymer is also a kind of polypropylene, and
the basic structure of its polymer chain is modified by adding
different kinds of monomer molecules. Ethylene is the most commonly
used monomer, which causes changes in the physical properties of
polypropylene. Compared with PP homopolymers, random copolymers
have improved optical properties (increased transparency and
reduced haze), improved impact resistance, increased flexibility,
and reduced melting temperature, thus reducing hot melt
temperature. At the same time, the chemical stability, water vapor
isolation properties and organ sensory properties (low odor and
taste) are basically the same as the homopolymer. Used in blow
molding, injection molding, extrusion, film and sheet extrusion
processing fields, authors with water pipes, food packaging
materials, pharmaceutical packaging materials and daily consumer
goods.
Key Advantages Over Standard PP
Tailored performance for niche applications.
Cost-effective alternative to engineering plastics like ABS or
nylon.
Retains PP’s inherent benefits (lightweight, chemical resistance)
while addressing weaknesses.
Product application in LED light field
Product application in Switch and Socket
Product application in Toilet-Seat
