Silicone Rubber Gask
Silicone Rubber Gaskets Polysiloxane (VMQ) Himsan Polymer is a recognized leading manufacturer of high quality silicone rubber gaskets, seals, and custom silicone products . Our company’s reputation for excellence has been built on our ability to provide our valued customers with the most effective designing, engineering and manufacturing solutions to meet their most demanding applications. Our main objective is to continuously exceed our customer’s expectations by providing them with high performance gaskets and sealing products, competitive pricing, on-time delivery and exceptional customer service. Himsan Polymer maintains a modern manufacturing facility along with knowledgeable, technically-oriented professionals enabling us to consistently meet all of your blueprint specifications and tolerance requirements. Silicone rubber is a high-performance elastomer with exceptional resistance to temperature extremes. Silicone molded and die cut gaskets remain functional within a temperature range of -67°F to +400°F, intermittent to +450°F. The low temperature flexibility of silicone is unmatched by any other elastomer. Silicone gaskets are often chosen due to their excellent resistance to chemicals, water, fire, fungal growth, ozone, heat and aging. Silicone has outstanding tensile strength, elongation, tear strength, and compression set. The versatility and long service life of silicone make it ideal for a wide variety of applications. Molded Silicone Gaskets Himsan Polymer specializes in the manufacturing of molded silicone gaskets and seals . We commonly mold products using silicone, fluorosilicone, and FDA (food grade) silicone compounds which are available in color options red/orange, black, gray, blue, white, and translucent with custom color compounding available upon request. Silicone rubber molding compounds durometer (hardness) typically ranges from 25 to 80 durometer, Shore A. Silicone rubber molding tolerances are compliant with rubber molding industry standard RMA A2 Precision tolerances. FDA (Food Grade) Silicone Gaskets and Seals Himsan Polymer produces precision die cut and molded FDA (Food Grade) silicone rubber gaskets and seals. Our FDA approved silicone products are fabricated to meet all of your blueprint specifications and tolerance requirements in order to suit your particular application. All food grade silicone products we manufacture are FDA compliant and provide reliable service at temperatures ranging from -175°F to 482°F. Food Grade (FDA) silicone is odorless, tasteless, peroxide-free, and fungus resistant making it ideal in applications where food is present. Fluorosilicone Gaskets and Seals (FVMQ) Himsan Polymer produces precision die cut and molded fluorosilicone rubber gaskets and seals . Similar to silicone, fluorosilicone (fluorinated silicone rubber) is intended for applications where there is contact with petroleum-based chemicals. However fluorosilicone can withstand more extreme temperatures and has superior chemical resistance properties to fuels, coolants and oils than standard silicone. Email:- info@himsanpolymer.com

Platinum Cure Silico
Platinum Cure Silicone V/S Peroxide Cure Silicone Platinum Cure Silicone Ø Platinum cure silicones will have better tensile strength and elongation properties than peroxide cure silicones. Ø The platinum compound would require a much shorter cycle time. Ø Compression set values of 30-40 per cent directly from the mold are common in platinum compounds, a brief post-cure cycle can usually improve this to 20-25 per cent. Ø Platinum Cured Silicone tubing offers many benefits over traditional peroxide cured tubing. Ø Platinum Tubing offers extremely high purity and very low leaching of bi-products. Due to the platinum catalyst curing system the crosslink density of the silicone polymer is altered which in turn offers enhanced physical propertie s along with ultra smooth surfaces, particularly useful in the bioprocess industry sector where reduced bacterial growth is an added benefit. Ø Platinum addition silicone tubing contains no phthalate plasticize rs associated with other types of tubing and is manufactured totally free from animal derived components . Ø Altimed Silicone Rubber Tubing is biocompatible to the ISO 10993 standard and meets fully USP Class VI, FDA, NSF and European Pharmacopoeia criteria. Platinum addition cured silicone offer the following benefits over peroxide cured materials:- 1) Predictable pump life 2) None yellowing 3) Free from cross linker by-products 4) Free from PCB’s (Poly Chlorinated Biphenyls) 5) Very tight surface cure 6) No impairment of odour or taste 7) Dry and non-sticky surface finish 8) Slightly greater clarity 9) Smoother surface and lower level of protein binding 10) Preferred by pharmaceutical and biotechnology industries 11) Fewer potential leachables 12) Better Transparency 13) Non reactive to body tissue and fluid 14) Non adherence to tissue 15) Unaffected by most water soluble materials 16) Sterilisable by steam, dry heat, ethylene oxide and gamma radiation 17) Resists oxidation, ozone and radiation 18) Indefinite shelf life 19) Does not support bacterial growth Disadvantages: 1) Shorter tubing life Peroxide Cure Silicone Ø Organic peroxides are commonly used with silicone rubber, such as 2,5 dimethyl- 2.5 di(t-butylperoxy) hexane, 2,4 dichloro-benzoyl peroxide, or dicumyl peroxide. Ø The polymer may be methyl- or vinyl-based. Peroxide-initiated cure is classified as a "second order" reaction, and has three steps When the elastomer is placed in the heated mold, the peroxide thermally decomposes to form free radicals; These free radicals attack either a methyl or vinyl group, depending on the specific polymer and peroxide used, to form active cross-link sites . The active sites on the silicone polymer then combine, forming a carbon-carbon bond. Ø peroxide cure silicones usually have better compression set properties for gaskets requiring critical long term sealing at extended temperatures Ø Peroxide Tubing is used extensively within the medical device market. Its combined strength and biocompatibility make it ideal for pumping applications where a long lifespan is required. a. Peristaltic Pump Tubing b. Partial and full contrast radio opaque tubing for x-ray detection c. Multi-lumen tubing and co-extruded tubing d. Restricted & Unrestricted Implantable materials e. Coloured Silicone Tubing using FDA approved pigments f. Greater physical compression capability g. Economical h. Longer Tubing life Disadvantages: Potential outgassing of peroxide products,in this if it not properly cured, or over long periods of time, outgassing of peroxides and ketones may occur. The major symptom of outgassing is blooming, or a fine white crystalline powder forming on the inside of the tubing. Silicone sheets without a post-cure will often have a sweet, distinctive odor – which may be dichlorobenzoyl peroxide.
