107 Silicone Rubber: 2026 Complete Guide for Properties, Applications and Sourcing
2026-07-20
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
Targeted at production engineers, procurement specialists and silicone product manufacturers, this guide delivers verified 2026 data, hands-on operation tips and trusted sourcing suggestions for 107 Silicone Rubber, to help you avoid common defects and reduce overall material cost by up to 18%.
What Is 107 Silicone Rubber: Core Definition and Basic Features
107 Silicone Rubber is a linear hydroxyl-terminated polydimethylsiloxane base polymer for making various cured silicone end products. As the most widely used raw material in the room temperature vulcanized (RTV) silicone industry, it accounts for over 62% of total unvulcanized silicone polymer consumption across global manufacturing sectors in 2026. In practice, Meiside’s production team finds that qualified 107 base rubber with consistent molecular weight distribution can reduce curing agent dosage by 12% compared with low-quality alternatives.
Q: What are the basic physical indicators of standard industrial 107 Silicone Rubber?
A: Standard grade 107 silicone rubber appears as colorless transparent viscous liquid, with hydroxyl content ranging from 0.05% to 0.2%, volatilization content less than 2% at 150℃, and no visible mechanical impurities after 24 hours of standing.
Q: How to correctly store unopened 107 Silicone Rubber for long shelf life?
A: Follow these 3 verified steps to extend the storage period for more than 12 months:
- Seal the packaging barrel tightly after each use to avoid contact with moisture in the air
- Place the material in a ventilated warehouse with constant temperature between 10℃ and 30℃, away from direct sunlight
- Do not store 107 silicone rubber together with amine, tin catalyst or crosslinking agent to avoid premature curing
| Viscosity Grade (25℃, mPa·s) | Volatile Content (%) | Elongation at Break of Cured Product (%) | Typical Application Scenario |
|---|---|---|---|
| 20 000 | ≤1.8 | 220 | Electronic potting adhesive |
| 50 000 | ≤1.5 | 350 | Construction sealant |
| 100 000 | ≤1.2 | 480 | Handmade mold silicone |
| 800 000 | ≤1.0 | 720 | High transparent human body simulation product |
The industry consensus in 2026 shows that 107 silicone rubber with volatilization content lower than 1.2% can extend the service life of cured silicone seals by more than 35% in high-temperature outdoor working environments.
Key Performance Advantages of Premium 107 Silicone Rubber
High-quality 107 silicone rubber produced by formal manufacturers has stable molecular chain structure, no harmful heavy metal residues, and can adapt to different curing process requirements. Actual testing shows that Meiside’s low-volatility 107 silicone series will not produce bubbling or cracking defects when cured at 80℃ for 2 hours.
Q: Why is low hydroxyl group uniformity a common disadvantage of inferior 107 silicone rubber?
A: If the molecular weight distribution of 107 silicone rubber is not uniform, partial crosslinking will occur during the curing process, resulting in uneven hardness of the final product, and the tensile strength will drop by more than 40% in long-term use.
Q: Can 107 Silicone Rubber meet food contact and medical grade requirements?
A: Yes, high-purity refined 107 silicone rubber without residual catalyst and low-molecular siloxane can pass FDA 21 CFR and EU RoHS certification, which is safe to use for food contact gaskets and medical auxiliary products.
Main Industrial Applications of 107 Silicone Rubber in 2026
From construction sealants to new energy battery thermal conductive pads, 107 silicone rubber has become the most indispensable base polymer for downstream silicone product manufacturing. From real cases of our cooperative clients in 2025-2026, the new energy industry’s demand for high-purity 107 silicone rubber has increased by 47% year on year.
Q: What is the largest consumption field of 107 Silicone Rubber at present?
A: The construction industry accounts for 48% of total 107 silicone rubber consumption, which is mainly used to produce weather-resistant silicone sealants for curtain wall installation, door and window caulking and outdoor component sealing.
Q: Can 107 Silicone Rubber be used to make silicone defoamer?
A: Low viscosity 107 silicone rubber below 10 000 mPa·s is the main raw material for producing industrial defoamer, which has good compatibility with water-based and oil-based systems and will not cause secondary pollution to production wastewater.
Purchasing Guidelines for High-Quality 107 Silicone Rubber
When you select 107 silicone rubber suppliers, you should not only focus on unit price, but also verify key indicators such as batch stability, volatilization content and after-sales technical support. 2026 silicone industry research data points out that unqualified 107 raw materials will cause an average of 21% of the production line shutdown loss for small silicone processing factories.
Frequently Asked Questions
Q1: What is the difference between 107 silicone rubber and raw silicone rubber HTV?
A: 107 silicone rubber is liquid hydroxyl-terminated base material for room temperature curing, while HTV raw rubber is high viscosity solid polymer for high temperature vulcanization processing, suitable for different production process scenarios.
Q2: How long is the normal shelf life of unopened 107 Silicone Rubber?
A: Qualified industrial grade 107 silicone rubber can keep stable performance for 12 months under recommended storage conditions. If the material is stored beyond the period, you can test the viscosity first before formal use.
Q3: Can 107 Silicone Rubber be customized for special viscosity requirements?
A: Formal silicone material manufacturers like Meiside can provide customized 107 silicone products with viscosity ranging from 1000 mPa·s to 1 million mPa·s to match different customer production formulas.
Q4: Will 107 Silicone Rubber cause corrosion to plastic or metal substrates?
A: Purified 107 silicone rubber without free acidic or alkaline substances is non-corrosive to most common metal and plastic substrates, and will not damage the surface of parts after long-term contact.
