Principle of Plastic Extrusion Equipment Introduced By Rubeer Extruder Machine Manufacturer
   Foaming extrusion: Thermoplastic elastomer tpv can be foamed by chemical and mechanical methods. For chemical foaming, foaming agents such as bihydrochloride can be used. The achievable foam density specific gravity ranges from 0.97 (typical unfoamed tpv) to 0.70. The lower density is affected by patents. Blowing agents will degrade at 180°C to 190°C, because most of the tpv base is...
