What is Liquid Silicone Rubber
Liquid Silicone Rubber (LSR) is a two-part catalysis-cured thermoset elastomer, we normally inject LSR materials into mold cavities to produce final silicone parts. This material provides properties not obtainable with TPE. Therefore, LSR is very versatile in elastomer industry, it is widely applied in various industries from consumer parts to medical devices. The normal operating temperature range of LSR is between -65â to 150â, shortly peaks to 260â. After solidify formation, LSR has very low compression set. These thermoset polymers are translucent,…
Thermoset vs Thermoplastic
Introduction Thermoset vs thermoplastic are two broad categories plastic materials in injection molding, the primary difference are different behaviors once heated. Thermoset is strengthened in the presence of heat, but it cannot be remolded or heated after the initial forming process. While thermoplastic can be reheated and remolded without any chemical alternations. Therefore, this gives rise to different physical and chemical properties of thermoset vs thermoplastic. Thermoplastic materials have low melting points, otherwise, thermoset parts can withstand high temperature without structural…
Medical Grade LSR
In medical industry, manufacturers never stop applying medical grade liquid silicone rubber for the best products with cost saving, high quality and extend lifetime performance. Furthermore, they should also focus on long-term cost and price stability to guarantee sales revenue and profit. The medical device market requires professional skill and research, especially in the area of material selection and manufacturing process. The material performance in medical industry are different between health and injury. Consequently, once you evaluate metal, plastic, ceramic…
Liquid Silicone Rubber vs High Consistency Rubber
Silicone Rubber Odorless ans tasteless silicone rubber is the most versatile engineering materials, it is widely applied to produce containers, elastic band, waterproofing materials and flexible tubing. Silicone rubber elastomer has unique characteristic of deforming and recovering under load, it can regain its original shape and size after bending, twisting, compressing and stretching. Therefore, its high elasticity is suitable for many component in commercial and industrial applications. In addition, silicone rubber is inert, this is non-reactive and safe for high…
LSR vs TPE
LSR vs TPE are the typical thermoset and thermoplastic materials. Thermoset and thermoplastic seam related but never interchangeable. LSR is thermoset, but TPE materials is thermoplastic. Each material has different material properties and inverse behavior in molding production process. Thermoplastic elastomer (TPE) and liquid silicone rubber (LSR) have similar properties, both of them are beneficial alternatives to natural or synthetic rubber. However, there are significant differences between thermoplastic elastomer (TPE) and thermoset elastomer (LSR) characteristics. What is LSR (Liquid Silicone Rubber)? Liquid…
Liquid Silicone Rubber Electricity
Introduction Ceramic and glass are the first material choice for medium and high voltage electrical applications, like high voltage insulators and lighting protectors. These materials have good electrical and outdoor exposure resistance without significantly deterioration. However, there are still some disadvantages of these materials, such as inability to handle certain stress, contamination in environment. These concerns encourage significant innovation in material science, especially in insulation materials and silicone rubber conductivity. Silicone rubber is a thermoset material, its molecular structure consists…
Food Grade LSR
Food grade liquid silicone rubber provides high strength and stress resistance to manufacture kitchen and household products, such as baking trays, bottle dispensers. It is also used for gasket and seal in industrial cooking appliances. There is no doubt that food-grade liquid silicone rubber encourage high quality and durability in bakeware and consumer goods to the widest world-wide market. Junle specializes in various volume of food-grade LSR for major manufacturers and international enterprises. With our 20 years experience and professional…
Difference Between Silicone and Latex Medical Devices
Introduction Medical device industry consist of a wide range of products and technology, these products are applied for diagnosis, mitigation, treatment, compensation, and prevention of disease and other conditions. The primary materials of medical device fabrication include silicone and latex. These two materials are thermoset plastic, both materials get permanent shapes by a chemical reaction. However, each material also has distinctive performance and applications. Bio-compatibility is the most important characteristics of materials for medical devices manufacturing. It ensures device’s ability…
Bio-compatibility of Liquid Silicone Rubber
Bio-compatibility Interactions Nowadays, we apply metals, ceramics, and polymers materials in medical devices to improve human health and life quality. The typical biological materials are polymers, natural rubbers, polyurethanes, and silicone rubbers. Therefore, we can formulate these materials for specific biomedical applications with unique characteristics. Liquid Silicone Rubber has excellent mechanical and chemical properties. Furthermore, it is also nontoxic, non-irritant and low cost. These desirable characteristics make it a perfect bio-material. Bio-material in definition is a synthetic or natural material in…
