107 Silicone Rubber: Full Properties, Applications and 2026 Usage Guide
2026-07-23
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 authoritative guide sorts out full verified information of 107 Silicone Rubber in 2026, supporting downstream manufacturing and procurement decision-making across 12+ industrial sectors.
What Exactly Is 107 Silicone Rubber
At the very beginning, 107 Silicone Rubber is a hydroxyl-terminated polydimethylsiloxane base polymer for room temperature vulcanized silicone products. It belongs to the most widely used raw material in the RTV-2 (two-component room temperature vulcanized silicone) production chain, with no additional volatile solvents under regular production standards.
107 Silicone Rubber is also named 107 hydroxyl silicone oil in many industrial scenarios, with molecular weight ranging from 10,000 to 800,000 under common commercial specifications. In practical production, Meiside’s 2026 test data shows that high-purity 107 silicone rubber from regular suppliers will not produce obvious pungent odor within the full vulcanization cycle. The industry consensus is that qualified 107 silicone rubber accounts for more than 62% of all raw material consumption for general RTV silicone products globally in 2026.
Q: What is the difference between 107 silicone rubber and ordinary silicone oil?
A: Unlike non-reactive dimethyl silicone oil, 107 silicone rubber has reactive hydroxyl groups at both molecular ends, which can crosslink with curing agents such as tetraethyl orthosilicate to form a stable elastic silicone structure after full reaction.
Q: Is 107 silicone rubber a dangerous chemical?
A: According to 2026 global chemical safety inventory data, unvulcanized 107 silicone rubber belongs to non-dangerous goods, with flash point higher than 200℃, no toxicity or corrosiveness under regular storage and use conditions.
Core Performance Parameters of Commercial 107 Silicone Rubber
Practical testing shows that different viscosity grades of 107 silicone rubber directly determine the hardness, elongation and tensile strength of final vulcanized products. 2026 field data from Meiside’s downstream 300+ cooperative manufacturers prove that parameter matching deviation of more than 12% will lead to 30% increase of defective rate of finished products.
| Viscosity Grade (25℃, mPa·s) | Typical Elongation of Vulcanizate (%) | Tensile Strength (MPa) | Main Application Scenario |
|---|---|---|---|
| 5,000 | 220 | 1.2 | General sealant raw material |
| 10,000 | 350 | 1.8 | Mold making base material |
| 50,000 | 520 | 2.3 | Concrete joint sealant |
| 800,000 | 780 | 3.1 | High-elastic shock pad raw material |
The 2026 Global Silicone Material Industry Research Report indicates that high-viscosity 107 silicone rubber above 100,000 mPa·s has achieved 18% cost reduction in mass production compared with 2022, greatly expanding its application in civil engineering fields.
Q: What is the shelf life of unopened 107 silicone rubber?
A: Under sealed storage conditions at 5-35℃ environment, the qualified 107 silicone rubber produced by formal manufacturers has a shelf life of 12 months, and the performance will not show obvious attenuation within 15 months under proper storage.
Q: Can 107 silicone rubber be used for food contact products?
A: Special food-grade modified 107 silicone rubber that passes FDA 21 CFR certification can be used for food contact scenarios, while ordinary industrial grade 107 silicone rubber is only applicable for common industrial sealing and mold making purposes.
Standard Processing Steps for 107 Silicone Rubber
From case studies of Meiside’s 200+ mold making clients, strictly following the standardized processing flow of 107 silicone rubber can reduce the vulcanization time by 25% on the premise of ensuring 100% qualified rate of finished products.
- Preheat the 107 silicone rubber raw material to 25±2℃, add the required amount of catalyst and stirring aid according to the production formula
- Stir the mixture at 300-500 rpm for 3-5 minutes, then place it in a vacuum chamber of -0.095MPa for 2-3 minutes to remove all mixed bubbles
- Pour the defoamed material into the pre-treated mold or construction base surface, and keep it at 20-30℃ for 12-24 hours to complete full vulcanization
- Demold or carry out subsequent processing after testing that the vulcanized material hardness reaches the preset standard value
Main Application Fields of 107 Silicone Rubber in 2026
Practical testing shows that 107 silicone rubber can be mixed with different fillers, color pastes and additives to produce finished products meeting diversified performance requirements, covering almost all scenes that need medium and low temperature elastic sealing materials.
Construction Engineering Sector
In 2026, more than 70% of the joint sealants for prefabricated buildings and curtain walls are produced with 107 silicone rubber as the main raw material, which has excellent weather resistance, and can keep stable performance for more than 20 years in outdoor -40℃ to 180℃ environment.
Industrial Mold Manufacturing Sector
Low and medium viscosity 107 silicone rubber is the core raw material of handmade molding silicone for craft, resin, and gypsum product production, with good copy precision up to 0.01mm, no deformation after repeated demolding for 100+ times.
Quality Screening Tips for 107 Silicone Rubber Procurement
In practical procurement practice, many unqualified low-cost 107 silicone rubber products add a large amount of white oil and low-value fillers, which will lead to problems such as serious shrinkage after vulcanization, and the elastic retention rate drops sharply after 1 year of use. The industry consensus is that formal manufacturers such as Meiside will provide full parameter test reports for each batch of 107 silicone rubber to help customers avoid quality risks.
Frequently Asked Questions
Q: Can 107 silicone rubber be cured at low temperature below 10℃?
A: Ordinary 107 silicone rubber vulcanization speed will drop sharply below 10℃, it is recommended to add 0.5-1% of dedicated low-temperature curing accelerator to ensure normal curing within 24 hours.
Q: What is the price range of 107 silicone rubber in 2026?
A: According to 2026 public industrial material data, the mainstream market price of regular industrial grade 107 silicone rubber ranges from 2.8 USD/kg to 5.2 USD/kg, depending on viscosity grade and certification level.
Q: Is 107 silicone rubber resistant to strong acid and strong corrosion?
A: Ordinary 107 silicone vulcanized products can only resist weak acid and weak alkali corrosion, if you need strong corrosion resistance, you need to add corresponding functional additives during processing.
Q: Can leftover 107 silicone rubber be recycled after vulcanization?
A: Vulcanized 107 silicone rubber forms an irreversible crosslinking structure, and can not be directly melted and recycled, you can process it into fine powder and add it to other low-demand silicone products as filler.
