Liquid Silicone Rubber Product Selection FAQ

Q1: What is the difference between tin‑cure silicone and platinum‑cure LSR?

A: Tin‑cure (condensation cure) is low‑cost for ordinary mold making, with slight shrinkage. Platinum‑cure (addition cure) is non‑toxic, food‑safe, low‑shrinkage, excellent tear resistance, for medical, food‑contact and high‑precision applications.

Q2: Can you customize liquid silicone formulas for my special requirements? 

A: Yes. We support custom hardness, viscosity, color, flame retardancy, high‑temperature resistance and other special performances. Please share your application, working conditions and target parameters.

Q3: What factors should I consider before buying LSR raw material? A: Key points: target hardness, working temperature, whether contact food/human body, mold type, required tear strength, shrinkage rate and mixing ratio.

Q4: Is high‑viscosity silicone better than low‑viscosity one?

A: Not exactly. Low‑viscosity LSR flows well for fine detailed molds. High‑viscosity silicone works better for large‑size casting. Choose viscosity based on your mold structure.

Q5: What factors affect liquid silicone mold quality?

A: Key factors include silicone hardness, curing system, viscosity, tear strength, shrinkage rate, mixing ratio, and operating temperature. We provide professional formula selection based on your finished product requirements.
