Bulk 107 Silicone Polymer CAS 70131-67-8 20 Ton FCL for Sealant Factory
Bulk 107 Silicone Polymer is hydroxyl‑terminated polydimethylsiloxane, CAS 70131‑67‑8. It is supplied in 20 ton FCL full container load for large‑scale sealant factory production. Strict quality inspection ensures stable viscosity and uniform hydroxyl content. It shows excellent compatibility with diverse fillers and neutral cross‑linkers, widely used as core base raw material for mass production of various one‑component and two‑component condensation‑cure silicone sealants.
Product Overview
Bulk 107 Silicone Polymer is hydroxyl‑terminated polydimethylsiloxane base polymer, CAS 70131‑67‑8. This full‑container bulk supply solution is specially tailored for large‑volume sealant manufacturers. Every batch undergoes strict testing on viscosity, hydroxyl value and impurity index. It adapts to continuous industrial kneading and production lines, supporting stable large‑batch manufacturing of multiple condensation‑cure silicone sealant products.
Key Features
- 20 Ton FCL full container bulk supply for sealant factory mass production
- Precisely controlled viscosity and stable hydroxyl terminal groups
- Excellent compatibility with mineral fillers and various silane cross‑linkers
- Low volatile impurities, outstanding batch‑to‑batch repeatability
- Optimized for continuous feeding of industrial sealant production lines
- Wide formula adaptability for acetic, neutral and special‑function sealants
- Strict pre‑shipment quality inspection for every full container load
Main Applications
- Bulk base polymer for large‑scale silicone sealant factory production
- Raw material for acetic, neutral, weatherproof and sanitary silicone sealant
- Base resin for construction‑grade and industrial‑grade silicone adhesive
- Condensation‑cure silicone compound mass manufacturing
- Large‑volume production of one‑part and two‑part RTV silicone products
Processing Suggestions
Complete material transfer, feeding and kneading operations under strictly moisture‑free environment. Avoid moisture contamination during container unloading and material pumping. Formulate together with corresponding cross‑linking agents, catalysts and functional fillers according to finished sealant formula. Prevent water ingress to avoid abnormal curing phenomenon.
Storage & Packing
Packed in standard sealed 200kg iron drums for 20‑ton FCL shipment. Store in cool, dry and well‑ventilated warehouse. Keep containers tightly sealed. Protect from moisture, high temperature and direct sunlight. Reseal drums promptly after partial material discharge. Follow recommended storage conditions to maintain polymer reactivity and valid shelf‑life.
