Identity and CAS
Record chemical name, CAS number where known, and whether the buyer needs LSR, HCR, or RTV. Similar commercial names can hide different vinyl content and inhibitor systems.
SPEC SPLIT FOR MATCHING WORK
Liquid silicone rubber manufacturers compared through a controlled field set
Matching work for liquid silicone rubber manufacturers starts with mix ratio, viscosity of each part, color, package type, quantity, US destination, and document requests. Silicone Rubber Sourcing identifies possible plants and equalizes answers. We do not manufacture, stock, or certify the quoted chemical.
Aqueous dispersions, RTV cartridges, millable HCR, and two-part LSR kits are not interchangeable quotes. If a respondent proposes another catalyst, pot life, or pail size, place that alternative on a separate line so the original request remains auditable. Matching work also records optional budget currency and whether the target is per kilogram, per pail, per drum, or for the whole order.
REQUIREMENT CARDS
Normalize LSR fields before any plant is ranked
High-end, mid-range, budget, or undecided is a buyer preference for documentation depth and commercial tightness, not a ranking this website has verified. Unknown viscosity or hardness should stay marked for supplier confirmation.
Viscosity and hardness
State requested viscosity, Shore hardness, density, and moisture. Leave unknown values marked for supplier confirmation against the exact quoted product rather than borrowing a family typical.
Package and UN number
Ask for pail, drum, cartridge, net contents, labeling, UN number, and DOT or IMDG statements that apply to the quoted kit and destination.
Documents and samples
Request current SDS, TDS, and CoA format for the proposed product. Sample purpose, method, and pass or fail criteria stay with the buyer and qualified reviewers.
SDS TDS COA QUESTIONS
Platinum-cure and peroxide-cure files are not substitutes
TSCA, REACH, GMP, or ISO statements are verification questions to the proposed supplier. They are not certifications held by this sourcing site. A file for another manufacturer or catalyst system is not evidence for the quote in hand.
| Document | Ask the supplier to confirm |
|---|---|
| Safety data sheet | Revision date, both kit parts, and that it matches the quoted product |
| Technical data sheet | Viscosity, hardness, density, pot life, and color method |
| Certificate of analysis | Lot format, test list, and whether a production CoA will match the sample |
| Transport note | UN number and classification for the exact package and destination |
NEXT STEP
Send liquid silicone rubber manufacturers a brief they can answer on one grid
State mix ratio, each-part viscosity, color, pail pairing, kilogram or kit quantity, US receiving point, and whether a sample CoA must match the production lot.
