Production Description
Polypropylene resin combines hydrocarbon resistance with autoclave sterilizability (up to 121°C). The material's crystallinity (40-60%) and tacticity (isotactic configuration) determine optical clarity and barrier properties. Common additives include nucleating agents, antistatics, and flame retardants for specialized grades.
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
