107 Silicone Rubber Base Polymer 200kg Drum CAS 70131‑67‑8 Bulk OH Terminated PDMS Raw Material
107 Silicone Rubber Base Polymer 200kg Drum is hydroxyl‑terminated polydimethylsiloxane with CAS 70131‑67‑8. Supplied in standard 200kg iron drum for bulk industrial usage. It features stable viscosity, consistent hydroxyl content and good filler compatibility. Widely used as base polymer for mass production of various condensation‑cure silicone products including sealants, adhesives and RTV silicone rubber.
Product Overview
107 Silicone Rubber Base Polymer is OH‑terminated polydimethylsiloxane, CAS 70131‑67‑8. This bulk industrial raw material is delivered in standard 200kg sealed iron drum. Strict production control ensures stable viscosity and uniform silanol content batch by batch. It is general‑purpose base polymer for condensation‑cure silicone system, meeting large‑volume formulation demand from sealant factories and silicone compound manufacturers.
Key Features
- Standard 200kg iron drum packaging for bulk industrial procurement
- Controlled viscosity and stable hydroxyl terminal groups
- Good compatibility with various fillers and silane cross‑linkers
- Low impurity, reliable batch‑to‑batch consistency
- Convenient for factory feeding and large‑scale continuous production
- Wide adaptability for multiple condensation‑cure silicone formulas
- Good storage stability under recommended conditions
Main Applications
- Bulk raw material for silicone sealant mass production
- Raw material for silicone adhesive and RTV silicone rubber
- Base polymer for silicone compound manufacturing
- Condensation‑cure silicone formulation for construction and industrial field
- Large‑scale production of one‑component and two‑component silicone products
Processing Suggestions
Operate feeding, transferring and mixing under moisture‑free condition. Avoid moisture ingress during drum opening and material transfer. Mix with cross‑linking agent, catalyst and fillers according to target product formula. Prevent water contamination to avoid premature cross‑linking and curing failure.
Storage & Packing
Packed in sealed 200kg iron drum. Store in cool, dry and ventilated warehouse. Keep drums tightly closed. Keep away from humidity, high temperature and direct sunlight. Reseal immediately after partial material take‑out. Proper storage guarantees product reactivity and shelf‑life.
