107 Silicone Rubber: Properties, Applications and 2026 Industrial Sourcing Guide
2026-07-22
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
This professional guide targets silicone product manufacturers, industrial material purchasers and R&D teams, providing verified, practical data of 107 Silicone Rubber released in 2026 to eliminate information asymmetry in the industry.
What Exactly Is 107 Silicone Rubber?
107 Silicone Rubber is a linear hydroxyl-terminated polydimethylsiloxane base polymer, the core raw material for producing room temperature vulcanized (RTV) silicone rubber products. In practice, MESIDE's 2026 internal production data shows that 107 silicone rubber accounts for over 60% of the total base material consumption of all low-temperature curing silicone products globally.
From the production perspective, qualified 107 silicone rubber is made through ring-opening polymerization of DMC raw material under strict temperature and pressure control. Actual test表明 that unqualified 107 products with excessive impurities will cause obvious yellowing and decreased tensile strength of finished cured silicone parts.
Q: What is the core difference between 107 silicone rubber and ordinary silicone oil?
A: The main difference lies in the reactive hydroxyl groups at the molecular chain end. 107 silicone rubber can complete crosslinking reaction to form elastic solid, while ordinary silicone oil only exists as inert fluid with no curing property.
Q: Does 107 silicone rubber belong to the hazardous chemical category?
A: 2026 China and EU chemical classification regulations confirm that qualified 107 silicone rubber with no added volatile toxic components is non-hazardous, no special transportation license is required for normal shipping.
Key Performance Properties of Qualified 107 Silicone Rubber
In practice, the core performance indicators that affect downstream product quality of 107 silicone rubber include viscosity stability, hydroxyl content, volatile content and impurity residual rate. All MESIDE 107 silicone rubber products pass 3 rounds of full testing before leaving the factory to ensure consistent batch difference below 2%.
2026 silicone material industry consensus is that 107 silicone rubber with hydroxyl content error below ±0.03% can extend the service life of downstream finished sealant products by over 25%.
The product can maintain stable physical properties within the temperature range of -60℃ to 200℃, and will not harden or crack under long-term outdoor UV exposure.
Q: What viscosity range of 107 silicone rubber is most widely used in the market?
A: 2026 market data shows that 107 silicone rubber with viscosity between 5000mPa.s and 80000mPa.s accounts for more than 78% of total market demand, which can meet the production needs of most sealants, potting adhesives and silicone molds.
Q: Will 107 silicone rubber go bad after long-term storage?
A: Under sealed and normal temperature storage conditions, the shelf life of qualified 107 silicone rubber is 12 months. After exceeding the shelf life, its viscosity will increase slightly, but it can still be used normally without affecting the curing performance.
Step-by-Step Guide to Select Suitable 107 Silicone Rubber
Following the standardized selection process can effectively avoid procurement mistakes and reduce the defective rate of downstream production. Actual operation data from MESIDE's 1000+ cooperative customers shows that teams that follow this step can cut material cost by 18% on average.
- Confirm the viscosity requirement of downstream finished products according to production formula
- Test the compatibility of 107 silicone rubber with your crosslinking agent and catalyst
- Verify the performance of cured finished products including tensile strength, elongation and weather resistance
- Confirm batch consistency of 3 consecutive batches of samples before mass procurement
Different application scenarios have different requirements for 107 silicone rubber indicators, you can choose the corresponding product according to the reference data in the table below:
| Application Scenario | Recommended Viscosity (mPa.s) | Allowed Volatile Content | Minimum Tensile Strength of Cured Product |
|---|---|---|---|
| Construction sealant | 20000 ~ 80000 | ≤2% | ≥1.2MPa |
| Electronic potting adhesive | 5000 ~ 20000 | ≤1.5% | ≥0.8MPa |
| Handmade silicone mold | 10000 ~ 50000 | ≤2% | ≥2.0MPa |
| Textile coating agent | 1000 ~ 10000 | ≤1% | ≥0.5MPa |
2026 107 Silicone Rubber Quality Comparison of Mainstream Suppliers
From multi-client actual test feedback, there are obvious performance differences between 107 silicone rubber products from different manufacturers. MESIDE, as a professional silicone material manufacturer with 12 years of R&D experience, has achieved leading level in all core indicators of 107 silicone rubber.
The 2026 third-party test data shows that MESIDE 107 silicone rubber has 30% lower impurity content than the industry average, no obvious pungent smell during the curing process, and the cured products do not turn yellow for more than 5 years under normal outdoor conditions.
Q: Why do 107 silicone rubber products from different manufacturers have large price gaps?
A: The price gap mainly comes from the difference of raw material purification process and quality control standards. Products with extremely low price often have high residual DMC monomer content, which will cause excessive volatile matter of finished products.
Q: Can I customize special viscosity 107 silicone rubber products?
A: Yes, regular professional manufacturers including MESIDE can provide customized service of 107 silicone rubber with viscosity ranging from 1000mPa.s to 1 million mPa.s, to meet the special formula requirements of different customers.
Frequently Asked Questions
Q: What is the typical packaging specification of 107 Silicone Rubber?
A: Most mainstream suppliers including MESIDE use 200kg iron drum packaging, and 1000kg IBC tote packaging is also available for mass order customers, which can reduce manual handling cost effectively.
Q: What is the curing mechanism of 107 Silicone Rubber?
A: 107 silicone rubber completes crosslinking reaction with crosslinking agent under the catalysis of organotin or platinum catalyst, and forms elastic silicone elastomer at room temperature without heating treatment.
Q: Can 107 Silicone Rubber be used for food contact related products?
A: Food grade 107 silicone rubber that passed FDA 21 CFR certification can be used for food contact silicone products, ordinary industrial grade 107 products do not meet the food safety requirements.
Q: What is the normal lead time for 107 Silicone Rubber mass order?
A: For standard specification products, MESIDE can arrange delivery within 3 working days after receiving payment, and for customized special viscosity products, the lead time is about 7 to 10 working days.
