From soft to tough and durable! Why has liquid silicone become a hot commodity in the medical, automotive, and maternal and infant fields?

Liquid silicone rubber solves material pain points in multiple industries with 3 major advantages

Medical catheter sensitization, the need to replace automotive seals every 3 years, and toxic release from mother-and-baby tableware — these material challenges that trouble industries are all solved by liquid silicone rubber through its “scene adaptability”. It is in a fluid state at room temperature and can be injection-molded into complex textured parts in one piece; after high-temperature curing, it possesses both “flexible fitting” and “structural toughness”, avoiding the problem of ordinary rubber being prone to cracking and breaking through the hardness limitation of plastics, thus becoming the preferred choice in medical, automotive, and household sectors.

1. Customizable hardness to fit scenarios
Different fields have significantly different hardness requirements: medical fetal heart rate monitoring probes need low hardness for fitting, and liquid silicone rubber can be adjusted to 30 Shore A. After a manufacturer used it, complaints about a sense of oppression decreased by 40%; automotive steering wheel anti-slip covers need high hardness for anti-slip purposes. After being adjusted to 70 Shore A, the grip is firm and non-slip, solving the “soft collapse” problem of traditional rubber.

2. Excellent weather resistance to extend service life
Liquid silicone rubber can withstand temperatures from -40℃ to 120℃: an automobile company used it for engine seals, which showed no aging or cracking for 5 years, doubling the service life compared to traditional rubber; outdoor lamp waterproof rings made of it did not become brittle or yellow after 3 years of exposure to the sun, significantly reducing maintenance costs.

3. Safety compliance to break through red lines
Liquid silicone rubber has passed FDA and LFGB certifications: when used in mother-and-baby teething toys, there are no harmful substances released during chewing, and allergy complaints of a certain brand have dropped to zero; when used on the inner wall of medical infusion catheters, skin irritation in patients is reduced by 60% compared to rubber catheters, complying with medical safety standards.
