Silicone Material Customization

Custom Silicone Products Manufacturer

Shengxin has a sound supplier management system to ensure the availability, consistency and reliability of rubber raw materials, providing a solid guarantee for the stable quality of products. We have established long – term partnerships with globally renowned brands of silicone raw materials, such as Wacker, Dow Silicones, Momentive, and Shin-Etsu. In response to the demands of different industries and complex application scenarios, Shengxin has the capability to jointly develop customized solutions with raw material suppliers.We conduct in depth optimization and verification of material formulations in terms of key properties such as mechanical strength, chemical resistance, flame – retardant performance, and airtightness, ensuring excellent performance in applications.

Silicone Material Customization for Industries

Silicone rubber is widely used in many industries due to its excellent high temperature resistance, corrosion resistance, non-toxicity and odorlessness. As one of Shengxin’s core services, we provide high-quality, customized silicone material solutions to meet the needs of medical, food, home and other fields.

Heat Resistance

Silicone materials can withstand high temperatures, typically ranging from -40°C to 230°C (-40°F to 446°F).

Flexibility and Elasticity

Silicone materials are highly flexible and elastic, allowing them to maintain their shape and properties over a wide range of temperatures and environmental conditions. This makes them suitable for applications that require durability and resilience, such as in seals, gaskets, and medical implants.

Biocompatibility

Silicone materials are biocompatible and are widely used in medical devices and implants, such as catheters, prosthetic devices, and breast implants.

Non-Toxicity

Silicones are generally non-toxic and inert, making them safe for use in food-contact applications such as cookware, baking molds, and kitchen utensils.

Transparency

Some silicone materials are transparent, allowing for optical applications such as lenses, optical fibers, and LED encapsulants.

Electrical Insulation

Silicone rubber has excellent electrical insulation properties, making it suitable for use in electrical and electronic components such as insulators, gaskets, and seals.

Chemical Resistance

Silicone materials are resistant to many chemicals, including oils, solvents, and acids, making them suitable for use in harsh environments such as industrial settings, laboratories, and automotive applications.

Silicone Material Customization & Exploration

1. Self-adhesive LSR

We develop different types self-adhesive LSR with different plastic (PC, PA, PBT, PPSU, etc.) achieving plastic-LSR 2K shots molding.
LSR 2k shots is an innovative molding process:
• After finishing plastic Injection molding then directly over-molding LSR in one machine.
• More clients require 2k shots molding due to stability and efficiency.

2 key points of LSR when using 2k shots molding:
• Self-adhesive (there is no time for painting primer)
• Fast curing @ low temperature (needs to balance the mold temperature of plastic and LSR)

2. Low temperature curing selective self-adhesive LSR

Applications:
Over molding with substrates which are not resistant to temperature. If the temperature is too high, it will cause:
• Electronics components – component damaged
• Some thermoplastic with low temperature resistance:
• ABS, PC/ABS, PCTG etc. – material deformation
• Anodized aluminum – oxide layer crack and color changes

Characteristics :
Fast Curing at low temperature (80oC) and keep workable pot-life.
• Pot-life 2hrs@25oC and > 36hrs@5oC
Five hardness levels – 30/40/50/60/70A

3. Highly transparent silicone

Silicone has many characteristics of high clarity, stability, design flexibility, and mechanical that can resist the influence of many external elements, making it an ideal outdoor solution for LED lighting systems. Over time, silicones have gradually become an alternative to glass and plastic lighting enclosures.

4. Antibacterial Series

Medical-grade products that meet SGS standards.

Our future development trends

FPC (Flexible Printed Circuit Board) is also new technology

Lower volume, lower weight, more ID possibilities.
• Application: wearable device, vehicle, 3C, medical, etc.
Need fast curing @ low temperature to avoid damaging electronic components.
• Need fast curing property (@ 80oC)

There’s no answer here for you? Please contact us and we will respond within 24 hours.

What materials do you use in your products?

Usually silicone/rubber/plastic/metal, other materials such as stainless steel, aluminum, copper, and brass are also used according to product design requirements.
Rubber：NR, SBR, BR, IR, NBR and other rubbers.
Silicone：Antibacterial, biocompatible medical silicone.
Plastic：ABS, PS, PP, PVC, PC and other plastics.

Do you have material certificates for your silicone?

We use clean and sustainable silicone materials that are certified by FDA and LFGB. If required, we will provide a raw silicone material test report.

Are silicone products safe for human?

Silicone is hypoallergenic, biocompatible (no adverse effects on the human), and chemical stability (highly inert). Therefore, silicone products are safe for human beings.

Do your materials meet European and American requirements?

Of course, before customizing silicone, we will ensure that the materials provided are safe and meet specific regulatory and quality standards. In addition, the materials we provide have passed many authoritative certifications in Europe and the United States, such as FDA, ROHS, DMF, LFGB, etc.
