Food-contact products
From silicone kitchenware and tubing to sealing components, select products for the compound, process and intended use. Confirm food-contact requirements for the specific grade and finished-part testing.
Explore applications and product selectionBaby-care and everyday silicone products
Consider transparency, surface condition and processing performance. Confirm finished-product compliance and antibacterial performance for the final formulation and intended use.
Explore applications and product selectionSeals and industrial components
For tubing, profiles, sealing rings and similar parts, review curing systems and supporting additives for extrusion or molding.
Explore applications and product selectionMedical accessories
Select the curing system for the specific part requirements, then determine whether an antibacterial additive and related testing are needed.
Explore applications and product selectionElectronic components
For keypads and similar parts, consider molding, surface condition and subsequent screen printing.
Explore applications and product selectionFrom development to production,
see the work behind the materials.
Laboratory operations, production equipment and packaging preparation provide a practical setting for technical discussions.
Understand the conditions
before your next trial.
Addition sequence, curing conditions and dosage vary by system. Connect every figure to the relevant material and process step.
Extrusion dosages and addition sequenceCheck fumed- and precipitated-silica compounds separately
Internal anti-blooming addition and finished-part treatment are separate processesDistinguish compounding from alcohol-dilution treatment
Screen printing or bonding after demolding?Review internal mold release dosage limits
Match the document to its intended use.
Review product instructions, safety data sheets and finished-part test reports separately. Request documents for the specific grade and application.
Example antibacterial test on a silicone product
The tested silicone pad was evaluated to GB/T 31402-2023 / ISO 22196. The results apply only to the sample identified in the report.
