Plastic is used in a broad range in many industries in their injection molding procedures. Plastics are a great option because they are light in weight, robust, flexible, and can take any desired shape.
Materials like thermoplastic cannot bear the high heat and may lose their shape. This is why producers have moved to liquid silicone rubber.
Liquid silicone rubber
Liquid silicone rubber is a dual-part silicone-reliant polymer combined using a chemical bond. It is used to create injection molded parts for different industries such as food, home and kitchen appliances, consumer products, and textiles.
When polymer is injection molded and heated, the catalyst starts a cross-connecting progression, which offers the substance robust strength and shape once curing happens.
The result is long-lasting, strong, and robust, making it a perfect option for several products involving electrical interfaces, automobile parts, hardware of appliances, and more.
Benefits of using LSR
Here are some benefits of using liquid silicone for molds:
Better heat bearing ability
LSR can bear temperatures up to 180 degrees Celsius without melting. They are ideal for heavy-duty and automobile applications such as gaskets and seals.
Low-temperature stability
Thermoplastic elastomers cannot bear extreme temperatures. At low temperatures, they get brittle and then crack. LSRs, however, are flexible in temperature at -50 degrees Celsius. They are a great option for any product you need to use at a low temperature.
Resistance to aging
Aging resistance is a major aspect of finding the right material for injection molding. Cured liquid silicone offers remarkable resistance to aging, depreciating, and UV rays. They can be used in places that need long-term exposure to elements of nature.
Resistance to chemicals
Liquid silicone offers low water absorption and remarkably chemical resistance when exposed to high temperatures.
Low compression setting
By low compression setting, we mean materials that can withstand deformation under consistent strain. LSR features a low compression setting ranging from 15 to 20%. They can retain flexibility when compressed for a long time and subjected to varied temperature ranges.
Better shelf life
The shelf life of LSR works as a major ingredient that makes it simple to use in a manufacturing unit. Most LSR products come with a shelf life of a minimum of one year.
Resistance to electricity
Electronic companies should know that the materials they will use to produce can hinder corona discharge. Liquid silicone rubber provides great resistance to electric stress without affecting the final product’s conductivity. This is why the materials can be used in high voltage and electrical applications.
It is important to know that you can get any product in any quantity. Right from silicone cup to silicone rings, houseware, and appliances, there is a wide range of products that you can order.
