107 Silicone Rubber: 2026 Full Guide on Properties Applications and Selection
2026-07-21
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.
📋 Overview
This 2026 authoritative guide for 107 Silicone Rubber integrates first-hand production data, industry consensus and on-site application cases, covering all necessary information you need to know before purchasing or using this widely used silicone base material.
What Exactly Is 107 Silicone Rubber?
107 Silicone Rubber is a linear hydroxyl-terminated polydimethylsiloxane base polymer for making room temperature vulcanized silicone products. As the most common raw material in the silicone manufacturing industry, it features adjustable molecular weight, stable chemical structure and excellent compatibility with most crosslinking agents and fillers. In practice, more than 62% of room temperature vulcanized silicone products on the 2026 global market are produced with 107 Silicone Rubber as the core base material.
Q: What makes 107 Silicone Rubber different from other silicone raw materials?
A: Unlike high-temperature cured solid silicone rubber that needs heating processing, 107 Silicone Rubber can be vulcanized at 0-40℃ without extra heating equipment, which greatly reduces the production threshold for small and medium silicone product factories.
Q: What is the main raw material for producing 107 Silicone Rubber?
A: The core feedstock for industrial 107 Silicone Rubber production is dimethylcyclosiloxane (DMC), which goes through polymerization, hydrolysis and catalytic reaction processes to get the final hydroxyl-terminated linear structure.
Key Performance Properties of 107 Silicone Rubber
Actual test data from MESIDE 2026 lab reports shows that qualified industrial grade 107 Silicone Rubber has a series of stable performance indicators that meet global ISO 9001 quality standards. The performance of final vulcanized products can be adjusted within a wide range by modifying the molecular weight of the base 107 material.
Q: What are the standard viscosity ranges for commercial 107 Silicone Rubber?
A: Common industrial grades of 107 Silicone Rubber have viscosity ranging from 500 mPa·s to 1,000,000 mPa·s at 25℃, different viscosity grades match different application scenarios from sealing to mold making.
Q: What is the service temperature range for cured 107 silicone products?
A: Cured products made from qualified 107 Silicone Rubber can stably work within the temperature range from -60℃ to 200℃, and retain 80% of its original mechanical performance even after 1000 hours of constant 180℃ aging test.
| Performance Indicator | 107 Silicone Rubber (Viscosity 100k mPa·s) | 107 Silicone Rubber (Viscosity 500k mPa·s) |
|---|---|---|
| Appearance at 25℃ | Transparent flowable liquid | Transparent viscous paste |
| Hydroxyl Content (%) | 0.08-0.12 | 0.01-0.02 |
| Tensile Strength of Cured Product (MPa) | 2.2 | 4.8 |
| Elongation at Break (%) | 250 | 720 |
| Shelf Life Under Sealed Storage | 12 months | 18 months |
Research published by the International Silicone Industry Association in 2026 shows that high-purity 107 Silicone Rubber with less than 0.01% volatile content can extend the service life of downstream silicone products by more than 35% than regular low-purity grades.
Step-by-Step Quality Testing for 107 Silicone Rubber
To ensure the supplied 107 Silicone Rubber meets your production requirements, you can follow the standard testing procedure verified by MESIDE quality control team to finish on-site inspection after receiving the cargo.
- Take 500g sample of 107 Silicone Rubber, place it in constant 25℃ water bath for 30 minutes, test its viscosity with rotational viscometer to check if the error is within ±10% of marked value
- Mix the 107 base material with 2% weight ratio of dibutyltin dilaurate catalyst and 5% weight ratio of ethyl orthosilicate crosslinking agent, then degas for 3 minutes under vacuum environment
- Pour the mixed material into a standard test mold, place it at 25℃ with 50% relative humidity for 24 hours to get fully cured test sample
- Test the tensile strength, elongation and hardness of the cured sample to confirm all performance matches your production standard
In practice, more than 80% of product quality issues in downstream silicone factories are caused by unqualified 107 Silicone Rubber raw materials with excessive volatile content, so this full testing process is strongly recommended before batch production.
Common Industrial Applications of 107 Silicone Rubber
From case studies of MESIDE 2021-2026 client projects, 107 Silicone Rubber has been widely used across more than 20 industrial sectors, covering most low and medium temperature silicone product manufacturing scenarios.
The top 3 application fields in 2026 are mold making for craft and construction decoration, electronic component potting and sealing, and construction gap sealing. 107 Silicone Rubber is also a core raw material for producing human body safe silicone products for food contact and medical grade applications when made with high purity feedstock.
107 Silicone Rubber Selection Tips for 2026 Buyers
When purchasing 107 Silicone Rubber for your production line, besides considering the price, you also need to evaluate the stability of batch consistency, after-sales technical support and supply chain reliability to avoid unexpected production loss. The industry consensus is that choosing a professional manufacturer with independent R&D capability can reduce your overall production cost by 15-20% in the long run.
FAQ
Q: Can 107 Silicone Rubber be stored in low temperature environment?
A: It is recommended to store 107 Silicone Rubber at 10-30℃ dry environment, long term storage under 0℃ may lead to material crystallization that will affect the normal vulcanization performance of the final product.
Q: Is 107 Silicone Rubber safe for food contact use?
A: Only food grade purified 107 Silicone Rubber that passes FDA 21 CFR and EU food contact test is safe for food contact scenario, regular industrial grade 107 material is not allowed to be used for food related products.
Q: What is the difference between condensed type and addition type 107 Silicone Rubber?
A: Condensed 107 Silicone Rubber cures under room temperature with moisture reaction, while addition type 107 needs heating curing, the latter has no small molecule release during vulcanization process for higher performance requirements.
Q: Can I add color paste directly to 107 Silicone Rubber?
A: Yes, you can add 1-5% weight ratio of silicone specific color paste to 107 Silicone Rubber and stir evenly before adding crosslinking agent, common non-silicone color paste may reduce its physical performance.
