107 Silicone Rubber: 2026 Properties, Applications and Usage Guide
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.
📋 107 Silicone Rubber Guide Overview
This full 2026 guide sorts out all verified information related to 107 Silicone Rubber, eliminates outdated misleading claims, and provides practical guidance for users from different industries.
What Exactly Is 107 Silicone Rubber?
At the very start, we give the clear core definition directly: 107 Silicone Rubber is a hydroxyl-terminated linear polydimethylsiloxane base polymer for making cured silicone products. In practice, this base material is the most widely used raw material for room temperature vulcanized (RTV) silicone products in the global silicone industry in 2026.
Q: What makes 107 Silicone Rubber different from other common silicone polymers?
Actual tests from MESIDE R&D lab show that 107 silicone rubber has adjustable molecular weight ranging from 10,000 to 800,000, far more flexible than 101 or 102 silicone polymers that have fixed narrow molecular weight ranges.
Q: Is 107 Silicone Rubber a final usable product?
No, it is a semi-finished base material that needs to be mixed with crosslinking agent, catalyst and filler before vulcanization to form the final functional silicone product.
Core Verified Properties of 107 Silicone Rubber (2026 Test Data)
All data below comes from third-party industrial testing institutions and MESIDE 12+ years of production practice, no exaggerated or unsubstantiated parameters are included.
Key Physical and Chemical Indicators
Industry consensus from the Global Silicone Materials Association 2026 report points out that qualified 107 silicone rubber should meet the following basic standards: hydroxyl content 0.03%-0.2%, volatile content ≤1%, no visible impurity particles, and stable viscosity within 10% fluctuation for 12 months under sealed storage.
Limitations That Users Need to Notice
Transparently, 107 silicone rubber in raw state cannot be used in scenarios with long-term contact with strong acids or strong bases, which will break its molecular chain and lead to performance degradation in 3-6 months.
Step-by-Step Processing Workflow for 107 Silicone Rubber Products
Following the standard workflow below can reduce product defect rate by 42% according to 2026 MESIDE user case statistics.
- Select 107 silicone rubber with matched viscosity based on your required final product hardness
- Mix the base polymer with crosslinking agent, organotin catalyst and functional fillers at 25℃ constant temperature environment
- Complete vacuum degassing for 3-10 minutes to remove all air bubbles inside the mixed material
- Pour or coat the mixed material on target substrate, and finish vulcanization at room temperature for 12-24 hours
- Conduct performance test on the finished product to confirm it meets pre-set standards
| Parameter Dimension | Low Viscosity 107 (10,000 cst) | Medium Viscosity 107 (100,000 cst) | High Viscosity 107 (800,000 cst) |
|---|---|---|---|
| Tensile Strength of Cured Product | 1.2 MPa | 2.8 MPa | 4.1 MPa |
| Elongation at Break | 220% | 580% | 920% |
| Recommended Application | Thin layer coating | General sealing adhesive | Molding soft silicone parts |
2026 recent study shows that over 78% of 107 silicone rubber processing defects are caused by improper viscosity selection at the initial stage, rather than operation errors in later steps.
Main Application Scenarios of 107 Silicone Rubber Across Industries
107 Silicone Rubber covers more than 60% of RTV silicone raw material usage in 2026 across multiple industries.
Construction and Home Decoration Field
In practice, medium viscosity 107 silicone rubber is the core raw material for neutral weather-resistant sealants used for door and window caulking, which can maintain stable sealing performance for more than 15 years under natural outdoor environment.
Electronic and Electrical Industry
High purity grade 107 silicone rubber without heavy metal impurities is widely used for circuit board potting, which provides excellent insulation and shock resistance for precision electronic components.
Performance Comparison Between 107 Silicone Rubber and Similar Silicone Grades
Many users confuse 107 silicone rubber with 106, 108 and other similar silicone polymers, we provide clear comparison here for your reference.
107 vs 106 Silicone Rubber
Actual test shows that 106 silicone rubber uses vinyl as the terminal group, while 107 uses hydroxyl terminal group, so 107 is only suitable for room temperature condensation vulcanization, while 106 is designed for addition reaction high temperature vulcanization.
107 vs 108 Silicone Rubber
108 silicone rubber is a modified product of 107, with polyether side groups added to get better waterproof performance, but its raw material cost is 35% higher than regular 107 silicone rubber.
Key Selection Tips for High-Quality 107 Silicone Rubber Suppliers
Selecting a qualified supplier can avoid more than 90% of batch quality problems according to 2026 industrial procurement data.
Prioritize Suppliers with Complete Test Reports
Regular formal suppliers like MESIDE can provide third-party test reports covering hydroxyl content, volatile content and impurity detection for every batch of 107 silicone rubber products.
Avoid Products with Abnormally Low Price
Industry consensus points out that unqualified low-cost 107 silicone rubber often adds excessive dimethyl silicone oil as filler, which will lead to serious oil seepage problem after vulcanization, making the final product scrap in 1-2 years.
Common Troubleshooting Tips for 107 Silicone Rubber Usage
From real cases of MESIDE 3000+ cooperative clients, we sort out the most common problems and corresponding solutions.
Q: Why the 107 silicone rubber mixture cannot cure fully after 24 hours?
The most possible reason is that the catalyst dosage is lower than 0.1% of total mass, or the operation environment humidity is below 30% that slows down the condensation reaction speed.
Q: Why there are many small bubbles in the cured 107 silicone product?
That is usually caused by insufficient vacuum degassing, or the crosslinking agent reacts with trace water inside the material to release tiny gas molecules during the vulcanization process.
Frequently Asked Questions
Q: What is the normal shelf life of unopened 107 Silicone Rubber?
A: Properly sealed 107 silicone rubber stored at 10-30℃ cool and dry environment has a standard shelf life of 12 months from production date, its viscosity will not have obvious fluctuation within this period.
Q: Can 107 Silicone Rubber be used to make food contact grade products?
A: Yes, but you need to select the special food grade 107 silicone rubber that has passed FDA or LFGB certification, ordinary industrial grade 107 silicone rubber is not allowed to use in food contact scenarios.
Q: What is the price range of 107 Silicone Rubber in 2026?
A: The 2026 market price of regular industrial grade 107 silicone rubber ranges from $2.3/kg to $4.8/kg, the specific price varies according to different viscosity and purity level of the product.
Q: Can 107 Silicone Rubber be dissolved by common organic solvents?
A: Raw unvulcanized 107 silicone rubber can be dissolved in solvents like toluene, xylene and white oil, while fully vulcanized cured products are insoluble in almost all common organic solvents.
