Compounding — Process Challenge

XLPE 및 고무용 과산화물 가교

전선·케이블, PE 폼, EPDM/실리콘 고무 가공업체는 폴리에틸렌과 탄성체를 자유기 가교시키기 위해 유기과산화물을 사용하며, 이는 수분/실란 경로의 대안입니다. 분해 온도와 스코치 안전성을 기준으로 선택하고, 보조제는 가교 밀도와 경화 효율을 높입니다.

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Formulation Workflow
1
Polymer & Process Definition
Identify the resin and process (extrusion, molding, film) and the targets — thermal stability, clarity, flame retardance, slip, or color.
2
Additive Selection
Match stabilizers, antioxidants, plasticizers, lubricants, flame retardants, or masterbatch carriers to the polymer and processing temperatures.
3
Compounding Trial
Confirm loading and dispersion on a compounding or molding trial, checking processability, mechanicals, and aesthetics against the control.
4
Validation & Scale-Up
Verify long-term performance (heat aging, migration, weathering) and lock the formulation, packaging, and lot specs for production.
