Product Features
  • Excellent elasticity and softness: Comfortable touch, good resilience, and wide selectable hardness range
  • Easy and efficient processing: Significantly simplifies production processes, shortens cycle time, improves productivity, and reduces manufacturing costs
  • Superior weather and chemical resistance: Excellent high and low temperature performance with wide service temperature range; good resistance to aging, ozone, and common chemical reagents
  • Outstanding colorability: Various bright and permanent colors can be formulated without painting, reducing costs and VOC emissions
  • Good sealing and shock absorption: Provides reliable anti-slip, shock absorption and sealing effects
  • Eco-friendly and non-toxic: Odor level meets Grade 3 or lower requirements
  • Strong adhesion to various materials: Selected grades can achieve overmolding with rigid plastics such as PP, ABS, PC and PA during injection molding
Instructions for Use
TPE is mainly processed using standard thermoplastic processing equipment, such as injection molding machines and extruders.
The core process can be summarized as: drying → heating and plasticizing → molding → cooling.
Before processing, it is recommended to dry the material at 70-80°C for 2-4 hours to avoid adverse effects on mechanical properties.
If dried material cannot be used immediately, it should be properly sealed to prevent moisture reabsorption.
Main processing methods for TPE include injection molding and extrusion molding.
Processing Notes
  • Before processing TPE of different colors or grades, thoroughly clean the barrel of the injection molding machine or extruder
  • PP or HDPE is recommended as purging material
  • During processing, ensure good ventilation in the working area
  • Operators shall wear appropriate protective equipment
Packaging and Storage
Packaging: 25 kg per bag, paper-plastic composite bag with PE film inner lining.
Storage: Store in a cool, dry and ventilated warehouse, away from direct sunlight and moisture.
Applications
  • Automotive industry: Weather strips, mudguards, dust covers, interior parts, floor mats, gearbox cushions
  • Consumer goods & tools: Power tools, soft-coated handles for household appliances, watch straps, shoe materials, sports equipment grips
  • Packaging materials: Breathing masks, seals, inner gaskets for bottle caps, food container gaskets
  • Industry & construction: Sealing strips, shock pads, coated hardware tools, water pipe gaskets
  • Wires & cables: Insulation and sheathing for halogen-free flame-retardant cable compounds
