Characteristics Of Silicone
The unique properties and versatility of silicone raw materials provide a range of advantages across various industries. Some key benefits include:
heat resistance: The silicone materials exhibit excellent thermal resistance, withstanding a wide temperature range from -40°C to 230°C (-40°F to 446°F).
Flexibility and Elasticity: The flexibility and elasticity of silicone materials enable them to maintain their shape and properties across a wide range of temperatures and environmental conditions, making them highly suitable for applications that demand durability and resilience, such as in seals, gaskets, and medical implants.
Biocompatibility: Silicone materials possess excellent biocompatibility and find extensive application in the field of medical devices and implants, including catheters, prosthetic devices, and breast implants.
Non-Toxicity: The use of silicones in food-contact applications, such as cookware, baking molds, and kitchen utensils, is considered safe due to their non-toxic and inert nature.
Transparency:The transparency of certain silicone materials enables their utilization in optical applications such as lenses, optical fibers, and LED encapsulants.
Electrical Insulation:The electrical insulation properties of silicone rubber are exceptional, rendering it highly suitable for application in electrical and electronic components such as insulators, gaskets, and seals.
Chemical Resistance:The silicone materials exhibit excellent chemical resistance, including oils, solvents, and acids, rendering them highly suitable for deployment in demanding environments such as industrial settings, laboratories, and automotive applications.
Application Of Silicone Raw Materials
1.Self-Adhesive LSR:
We can provide various types of self-adhesive LSR with different plastics (PC, PA, PBT, PPSU, etc.) to achieve plastic-LSR 2K shots molding.
2.LSR 2k shots is an innovative molding process:
- It involves directly over-molding LSR onto finished plastic injection molded parts in a single machine.
- The demand for 2k shots molding has increased due to its stability and efficiency.
3.There are two key points to consider when using LSR in 2k shots molding:
- The self-adhesive nature eliminates the need for painting primer.
- Fast curing at low temperatures is required to balance the mold temperature of both plastic and LSR.
4.Low Temperature Curing Selective Self-Adhesive LSR
Applications: Over molding with substrates that have low temperature resistance. Excessive temperatures may result in the following issues:
-Damage to electronic components.
-Deformation of thermoplastics with low temperature resistance, such as ABS, PC/ABS, PCTG, etc.
-Cracking and color changes in anodized aluminum oxide layer.
Characteristics:
- Fast curing at a low temperature (80°C) while maintaining a workable pot-life.
-Pot-life is 2 hours at 25°C and over 36 hours at 5°C.
-Five hardness levels available - 30/40/50/60/70A.
-Fast curing at a low temperature requires careful balancing of the mold temperature for both plastic and LSR.
5.Highly Transparent Silicone
Silicone, with its high transparency, stability, design flexibility, and mechanical resistance to external elements, has become an ideal outdoor solution for LED lighting systems. As a result, silicone has gradually emerged as a viable alternative to glass and plastic enclosures in the lighting industry.
6.Antibacterial Series
Medical grades that are qualified to meet ISO 10993 biocompatibility standards include:
Cytotoxicity (ISO 10993-5: 2009)
Sensitization (ISO 10993-10: 2010)
Intracutaneous reactivity (ISO 10993-10: 2019)
Systemic toxicity and subchronic toxicity (ISO 10993-11: 2017)
Hemocompatibility (ISO 10993-4: 2017)
Genotoxicity (ISO 10993-4: 2017)
Advantages of Food Grade Silicone Rubber:
Colosilicone offers a variety of products tailored for specific food and beverage applications. Compared to rubber and other materials, LSR (Liquid Silicone Rubber) provides several advantages:
Durability: Food grade LSR parts are flame retardant, corrosion-resistant, and durable enough for the demands of busy kitchens or manufacturing facilities. They easily absorb vibrations, are exceptionally pure, and have a low compression set.
Process Flexibility: LSR parts can be made using conventional and 2-shot injection molding, offering greater design flexibility and more manufacturing options. Contact SIMTEC to learn more about our technical capabilities.
Heat and Cold Resistance: Food grade LSR maintains its properties in extreme temperatures, ensuring more reliable equipment and durable products, crucial for food and beverage applications.
Bacterial and Chemical Resistance: LSR is chemically inert and resists bacteria and mold growth, ensuring compliance with HACCP best practices and reducing supply chain risks.
FDA Compliance: LSR is an excellent choice for meeting FDA regulations for food and beverage products.
In summary, food grade silicone rubber is versatile and resistant to extreme temperatures, making it ideal for use from home kitchens to industrial plants. FDA-approved food-grade silicone is available for applications requiring high resistance to chemical and bacterial contamination.
