Silicone Material Knowledge

What are the types of silicone rubber and what products suit each?

Silicone rubber is generally divided into solid silicone rubber and liquid silicone rubber (LSR). Solid silicone suits compression molding for structural parts, gaskets and buttons. LSR suits injection molding with better flow and higher precision, and is commonly used for baby feeding, medical grade and fine-structure products.

What silicone material grades does WQ Silicone offer?

Available grades at WQ Silicone include food grade silicone (VMQ), industrial grade silicone, high temperature resistant silicone, low temperature resistant silicone, flame retardant silicone and medical grade silicone, all compliant with international environmental standards.

What is antibacterial silicone and where is it used?

Antibacterial silicone is silicone compounded with antimicrobial additives, supported by antibacterial material MSDS and test reports. It suits elderly care products, products used in public areas, and baby or personal care items with high hygiene requirements.

How do you solve odor and parting line problems in silicone products?

Odor in silicone products is reduced by using low-odor food grade raw material and applying post-curing. Parting lines are controlled through proper mold structure design and precision machining, followed by manual deflashing. A feel-enhancing oil coating can be applied to reduce dust attraction and improve hand feel.

How long do silicone products last?

Silicone products made with 100% food grade raw material are non-toxic, free of heavy metals, and offer better antibacterial performance and ductility, with a service life of more than 3 years under normal use.

Packaging & Shipping

Can packaging be customized?

Packaging customization at WQ Silicone covers color boxes and inner cartons. If you have artwork we use it directly; if not, our design team can create it based on your content. For transport we use high-quality cartons with protective corners and woven bag waterproofing to reduce deformation and damage risk.
