Custom Formulation:
What information is required to develop a custom compound?
To prepare a formulation, we need your target hardness (Shore A), color, curing system (peroxide or platinum), processing method (extrusion, molding, or coating), and any special property requirements such as flame retardancy, conductivity, or oil resistance. If available, application details and expected working conditions (temperature, medium exposure) help us fine-tune the compound.
Do you provide FDA or medical-grade silicone materials?
Yes. We offer medical and healthcare-grade silicone compounds formulated with FDA-compliant raw materials and produced under controlled manufacturing and quality assurance systems suitable for medical product development and regulatory testing.
What is the lead time for a custom sample?
Typical sample development takes 7–14 working days after receiving complete formulation details and technical confirmation. Complex formulations or new pigment matching may require additional validation time.
What is the minimum order quantity (MOQ)?
For production batches, the standard MOQ is 20 kg, depending on compound type and pigment load. Smaller pilot or sample quantities are available for testing and validation before bulk production.
