Silicone Rubber Products Engineered for Performance.
Yakows provides silicone rubber materials and custom silicone compounds for molding, extrusion, sheeting, sealing and precision manufacturing. Our silicone rubber product range includes HTV silicone rubber, liquid silicone rubber (LSR), RTV silicone and application-specific compounds for electrical, automotive, medical, food-contact and industrial applications.
Silicone Rubber Materials for Industrial Manufacturing
Silicone rubber is widely used to manufacture flexible seals, gaskets, O-rings, tubing, profiles, sheets, electrical insulation components and precision molded parts. Depending on the manufacturing process, silicone materials may be supplied as solid silicone rubber, high-temperature vulcanized silicone rubber, liquid silicone rubber or room-temperature-curing silicone.
For manufacturers, selecting a silicone rubber product is not only a question of hardness. Processing method, curing system, flow behavior, tear strength, compression performance, temperature exposure, weathering, electrical requirements and regulatory documentation can all influence material selection.
HTV silicone rubber, also referred to as solid silicone rubber or HCR silicone, is commonly selected for compression molding, extrusion, calendering and molded rubber components. Different formulations can be developed for general-purpose, high-strength, flame-retardant, food-contact, medical and electrical applications.
Liquid silicone rubber (LSR) is designed for liquid injection molding and precision manufacturing. It is particularly suitable when production requires automated processing, detailed part geometry, repeatable molding quality and efficient high-volume production.
RTV silicone rubber cures without the same high-temperature molding process used for HTV or LSR. RTV materials are commonly considered for sealing, bonding, encapsulation, potting, repair and mold-making applications.
YakSil supports manufacturers that require silicone rubber for molding, silicone rubber sheeting, silicone for O-rings, extrusion profiles, insulation parts and custom industrial silicone applications. Material recommendations can be based on your processing method, product design and operating environment.
Three Silicone Platforms. Different Processing Logic.
Understanding the difference between HTV, liquid silicone rubber and RTV silicone helps manufacturers select a material that works with the intended production process and finished-part performance requirements.
HTV Silicone Rubber
High-temperature vulcanized silicone rubber is a solid silicone elastomer designed for heat-curing processes. HTV silicone can be formulated for molding, extrusion, calendering and other industrial silicone rubber processing methods.

Why Manufacturers Choose Silicone Rubber
Silicone rubber combines environmental durability, flexibility and processing versatility. Actual properties depend on the formulation, curing system, hardness and application grade.
Wide Temperature Capability
Silicone rubber is commonly selected where conventional elastomers may lose flexibility or performance under elevated or low-temperature service conditions.
UV, Ozone & Weather Resistance
Silicone materials are widely used in outdoor components because of their resistance to ozone, sunlight, moisture and long-term environmental exposure.
Electrical Insulation
Suitable silicone formulations can provide stable electrical insulation performance for cable accessories, protective components and high-voltage insulation applications.
Flexible Sealing Performance
Silicone elastomers can maintain softness and elastic recovery, making them useful for seals, O-rings, gaskets and flexible contact components.
Mechanical Property Options
Formulations can be selected according to hardness, tensile strength, tear resistance, elongation and compression requirements.
Specialized Silicone Grades
Material systems can be developed for medical, food-contact, flame-retardant, electrical, high-strength and other application-specific requirements.
How to Select Silicone Rubber by Manufacturing Process
The production method is one of the fastest ways to narrow down the right silicone material. Use this comparison as a starting point before evaluating final mechanical, regulatory and application requirements.
| Manufacturing Process | Recommended Silicone | Typical Products | Key Selection Focus |
|---|---|---|---|
| Compression Molding | HTV / HCR | O-rings, seals, gaskets, plugs, covers, pads and molded parts | Flow, mold release, cure, tear strength and compression behavior |
| Liquid Injection Molding | LSR | Precision components, valves, diaphragms and complex molded parts | Injection behavior, cure speed, precision and production repeatability |
| Extrusion | Extrusion HTV | Silicone tubing, profiles, cords, strips and cable components | Extrusion stability, surface, dimensional consistency and cure |
| Calendering | Sheeting HTV | Silicone sheets, insulation pads, die-cut gaskets and membranes | Sheet uniformity, thickness, tensile and surface quality |
| Potting / Encapsulation | RTV Silicone | Electronic assemblies, electrical protection and encapsulation | Cure system, viscosity, adhesion and application environment |
| Bonding / Repair | RTV / Silicone Adhesive | Silicone bonding, sealing and maintenance applications | Surface preparation, adhesion and curing conditions |
