More About Custom Silicone Products

The manufacturing process of silicone products usually includes mixing, molding, vulcanization (curing) and post-processing steps. The cost of seven molds is lower than that of plastic products.

Silicone is a synthetic polymer material composed of silicon, oxygen, carbon, and hydrogen. It has many forms, such as liquid, gel, and rubber-like materials, and is widely used in various fields due to its excellent physical and chemical properties.

Features of Silicone
High and low temperature resistance: Silicone can maintain stable performance in the temperature range of -60°C to +250°C.
Weather resistance: Silicone has excellent resistance to UV, oxidation, and ozone.
Electrical insulation: Silicone has good insulation properties and is an ideal electrical insulation material.
Flexibility and elasticity: Silicone has good flexibility and elasticity and is not easy to deform and break.
Biocompatibility: Silicone is non-toxic and odorless, harmless to the human body, and widely used in the medical and food industries.
Classification of Silicone
Silicone can be divided into many types according to its form and use:

Room temperature vulcanized silicone (RTV): mainly used for sealing, bonding and coating. Common RTV silicones include sealants and mold silicones.
High temperature vulcanized silicone (HTV): used to make silicone rubber products such as silicone tubes, silicone gaskets and silicone seals.
Liquid silicone (LSR): products made of complex shapes through injection molding process, commonly used in medical devices and baby products.
Silicone oil and silicone grease: used for lubrication, insulation and heat dissipation.
Application of silicone
Industry: used for sealing, insulation and waterproofing, such as automotive sealing strips, building sealants and electronic component packaging.
Medical: used to make medical devices, prostheses, catheters and contact lenses, etc.
Food: used to make food molds, baking tools and baby pacifiers, etc.
Daily necessities: used to make silicone watch straps, silicone mobile phone cases, kitchen utensils, etc.

Silicone is a non-toxic, odorless, synthetic polymer with good biocompatibility. Silicone is widely used in food, medical, baby products, and other applications that come into contact with the human body, proving that it is safe for the human body. For example, baking molds, baby pacifiers, and medical devices made of silicone are all rigorously tested.

Comparison of Silicone and Plastic
Silicon and plastic differ greatly in chemical composition, physical properties, and application areas. Here are their main differences:

Chemical Composition
Silicon: A polymer composed mainly of silicon, oxygen, carbon, and hydrogen.
Plastic: A polymer composed mainly of carbon and hydrogen. Common types of plastics include polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyvinyl chloride (PVC).
Physical Properties
Temperature Resistance: Silicone has excellent resistance to high and low temperatures and can be used in the range of -60°C to +250°C. The temperature resistance of plastics varies from type to type, but is generally not as good as silicone.
Elasticity: Silicone has good elasticity and flexibility, while the elasticity of plastics varies from type to type.
Biocompatibility: Silicone has good biocompatibility and is often used in the medical and food fields. Plastics have poor biocompatibility, and some plastics may release harmful substances under certain conditions.
Application fields
Silicone: Widely used in medical, food, baby products, seals, electronic components and baking tools.
Plastics: Widely used, including packaging materials, building materials, household items, toys and electronic equipment casings.
Environmental impact
Silicone: Silicone is biodegradable and relatively environmentally friendly, but its production process may involve high energy consumption.
Plastics: Most plastics are not easy to degrade, causing serious environmental pollution problems, especially the impact of plastic waste and microplastics on the ecosystem.

Yes, silicone can go in the oven. Silicone bakeware and kitchen utensils are designed to withstand high temperatures, typically up to 450°F (232°C) or even higher. Here are some important considerations and tips for using silicone in the oven

Growjaa is a food grade silicone supplier manufacturer.

Characteristics and Benefits:
Food grade silicone is non-toxic and temperature resistance: It can withstand a wide range of temperatures, typically from -40°F to 450°F (-40°C to 232°C). Non-Stick Properties: The smooth, non-porous surface of silicone prevents food from sticking, making it easy to clean.

Common Uses:
Bakeware: Silicone molds and baking mats are popular because they provide even heat distribution and easy release of baked goods.

Utensils: Spatulas, tongs, and whisks made from silicone are heat-resistant and gentle on non-stick cookware surfaces.

Storage Solutions: Silicone food storage bags and lids are reusable, providing an eco-friendly alternative to single-use plastics.

Baby Products: Due to its safety and softness, food grade silicone is often used for baby bottles, pacifiers, and teething toys.

Kitchen Gadgets: Items such as ice cube trays, steamers, and colanders benefit from the material’s flexibility and durability.

Liquid Silicone Rubber (LSR) is a high-purity, high-performance silicon-based material. It exists in liquid form and is made into a variety of products through injection molding. LSR is known for its excellent elasticity, heat resistance and biocompatibility, and is widely used in many industries such as medical, food, electronics and automobiles.

Common uses:
Medical devices: Due to its biocompatibility and high-temperature sterilization resistance, LSR is used to manufacture catheters, seals, medical tubing and artificial organs.

Food contact products: Used to make baking molds, pacifiers, baby bottles, kitchen utensils and seals.

Electronic and electrical components: Seals, insulators and connectors made of LSR are widely used in electronic devices.

Automotive industry: Sealing gaskets, connectors and cable sheaths in automobiles all use LSR to ensure durability and reliability.

Daily necessities: Used to make watch straps, swimming goggles, waterproof mobile phone cases, etc.

Liquid Silicone Rubber Manufacturing Process:
Liquid Silicone Rubber is processed by injection molding process:
Mixing: LSR usually consists of two parts, which need to be mixed evenly before processing.
Injection: The mixed liquid silicone rubber is injected into the mold through the injection molding machine.
Curing: In the mold, LSR is quickly cured at high temperature.
Demolding: After curing is completed, the finished product is removed from the mold for subsequent processing or assembly.

Silicone Nipples and bottles: Silicone nipples and bottles are popular because of their safety, non-toxicity and high temperature resistance.
Silicone Teething: Silicone teething gel is soft, bite-resistant and does not release harmful substances. It is an important tool for babies to relieve teething discomfort.
Silicone baking molds: Silicone baking molds are widely used in the production of cakes, biscuits and other baked products because of their high temperature resistance, good flexibility and non-stick properties.
Silicone food storage bags: Silicone food storage bags are environmentally friendly, durable and reusable, gradually replacing disposable plastic bags.
Medical catheters and seals: Due to its biocompatibility and high temperature sterilization resistance, silicone is widely used in the manufacture of catheters, seals and other medical devices (Rubber World).
Medical implants: Silicone is often used to manufacture medical implants such as prostheses and fillers due to its good compatibility with human tissues.
Seals and gaskets: Silicone is often used to manufacture seals and gaskets for various mechanical equipment due to its chemical resistance and high temperature performance. It is widely used in industries such as automobiles, aerospace and construction.
There are also restrictions on the most popular beauty and personal care industry and pet industry on the application of silicone materials is becoming more and more popular, such as silicone ice rooler, silicone dog slow feeding mat, foldable silicone bowl and so on.
