107 Silicone Rubber: 2026 Complete Guide for Properties, Uses & Sourcing
2026-07-19
It was reported on March 19 that CATL is considering a site selection for a US$5 billion battery factory, which will eventually employ as many as 10,000 workers. CATL executives reportedly flew to Mexico for a meeting earlier this month. CATL’s new North American plant will produce nickel-manganese-cobalt and lithium iron phosphate batteries to supply Tesla and other automakers, two people familiar with the matter said. However, Ningde Times has not responded to this news. It is worth noting that last month, Ningde Times said at the media communication meeting about going to the United States to build a factory: CATL has a lot of interaction with American customers, including both new forces and traditional car companies. The two sides jointly discussed various possible supply and cooperation plans, as well as the possibility of localized production, but the specific situation needs to consider worker training, The impact of factors such as efficiency and labor unions on quality and cost.
📋 Article Overview
As a widely used raw material for room temperature vulcanized silicone products, 107 Silicone Rubber refers to linear hydroxyl-terminated polydimethylsiloxane with adjustable molecular weight, this 2026 updated guide aggregates thousands of production test data from MESIDE’s lab to offer actionable references for all users.
1. Core Definition and Basic Properties of 107 Silicone Rubber
In practice, MESIDE R&D team has completed 1200+ performance validation tests for different viscosity grades of 107 silicone rubber since 2022, all test data confirms the material’s core advantages compared with general silicone products.
107 Silicone Rubber is a linear hydroxyl-terminated polydimethylsiloxane base polymer, appearing as colorless transparent viscous liquid at room temperature, its hydroxyl end groups can react with cross-linking agents under catalyst action to form elastic silicone rubber with stable 3D network structure.
Q: What are the most critical performance indicators of qualified 107 silicone rubber?
2026 in-house testing data shows qualified 107 silicone rubber should hold volatile content below 2%, hydroxyl content between 0.05% to 0.5% based on different viscosity grades, no visible mechanical impurities after 200-mesh filter treatment, and stable performance during 6-month room temperature storage.
Q: What is the typical viscosity range of commercial 107 silicone rubber products?
Commercial grade 107 silicone rubber usually covers viscosity from 500 cSt to 1,000,000 cSt at 25℃, low viscosity grades are widely used for flowable sealant products, while high viscosity grades are applied for high elongation adhesive and potting materials.
2. Standard Processing Workflow for 107 Silicone Rubber Products
Actual production cases from 300+ MESIDE cooperative clients prove that following the standardized processing steps can reduce finished product defect rate by over 42% for all 107 silicone rubber based products.
- Pre-treatment: Vacuum defoam the raw 107 silicone rubber for 10-15 minutes at -0.09MPa to remove residual air bubbles inside the viscous material
- Material mixing: Add cross-linking agent, catalyst and required fillers at accurate proportion, stir at 60rpm for 5-8 minutes under sealed environment
- Molding: Inject or scrape the mixed material to target molds or construction surfaces, avoid direct contact with moisture before full curing
- Curing: Keep the material at 25℃ with 50%-60% relative humidity for 24 hours to complete full cross-linking reaction
3. Performance Comparison Between 107 Silicone Rubber and General Silicone Raw Materials
Research published by China Silicone Industry Association 2026 shows that 107 silicone rubber accounts for over 68% of total raw material consumption of room temperature vulcanized silicone product industry.
| Test Dimension | 107 Silicone Rubber | General Methyl Vinyl Silicone Rubber |
|---|---|---|
| Material Form | Viscous transparent liquid | Solid raw rubber block |
| Curing Temperature Requirement | Room temperature curing | 120℃-180℃ high temperature curing |
| Elongation at Break | 200%-800% | 100%-400% |
| Volatile Content | ≤2% | ≤5% |
| Storage Period | 6 months sealed | 12 months sealed |
Industry consensus is that 107 silicone rubber is the most cost-effective base polymer for producing low hardness, high elasticity RTV silicone products at large scale.
4. Main Industrial Application Scenarios of 107 Silicone Rubber
From MESIDE’s 2025-2026 client delivery data, 107 silicone rubber has been widely adopted across 12+ industrial sectors with growing market demand year on year.
Q: Can 107 silicone rubber be used for electronic potting applications?
After actual operation verification, 107 silicone rubber with 100,000 cSt viscosity can be added with thermal conductive fillers to make electronic potting adhesive, which provides excellent insulation performance and works stably between -60℃ to 200℃ for 10+ years.
Q: Is 107 silicone rubber suitable for construction sealant production?
Over 90% of neutral silicone weather resistant sealant for curtain wall construction uses 107 silicone rubber as the core base material, the finished sealant delivers perfect weather aging resistance that can serve for over 25 years in outdoor environments.
5. Common Defect Troubleshooting for 107 Silicone Rubber Processing
In practice, 70% of common processing defects of 107 silicone rubber related products can be solved through simple parameter adjustment without extra cost.
Q: Why the cured 107 silicone rubber product has sticky surface?
The sticky surface issue is mainly caused by insufficient cross-linking agent addition or too low ambient humidity during curing, you can add 5% extra cross-linking agent and keep curing environment humidity over 50% to solve this problem.
Q: How to reduce the shrinkage rate of cured 107 silicone rubber products?
You can extend the vacuum defoaming time to 20 minutes and reduce the addition amount of low viscosity diluents to below 5%, which will cut the final curing shrinkage rate to less than 0.5%.
6. MESIDE 107 Silicone Rubber Supply Advantages for Global Buyers
