    Momentive Performance MaterialsSilopren™ LSR 2650
    • Tear Strength:50.0 - 50.0 kN/m
    Silopren™ LSR 2650 is a two-component liquid silicone rubber for injection molding processes. In comparison to Silopren™ LSR 2050, Silopren™ LSR 2650 shows a lower viscosity, improved tear resistance and a higher reactivity. Therefore, it is also possible to reduce the vulcanization temperature while maintaining a standard crosslinking rate. The increased reactivity does not affect the properties of the vulcanizate.Key Features and BenefitsVulcanizates of Silopren™ LSR 2650 are typically distinguished by the following properties: High reactivity, lower viscosity, shorter cycle time Excellent thermal stability Biocompatible Sterilizable with ethylene oxide, steam and gamma radiation High stability and flexibility at low temperatures Good rubber-like properties, high tear resistance Long service life at dynamic stress High stability to ozone and ultraviolet light Outstanding resistance to aging Excellent dielectric behavior over a wide range of temperatures Easily pigmentable with LSR color pastes KTW approved Potential ApplicationsBecause of its outstanding properties, Silopren™ LSR 2650 is an excellent candidate to consider for the following elastomeric articles: Sealing elements O-rings Stoppers Diaphragms Keypads Bellows Catheters Pacifiers Baby teats Respiratory devices Vibration dampers Air vent flaps Switch cover Breast shields Nose pads Pressure cookers parts Spark plug boots Cable connectors Catheters, parts of medical technical equipment s.o.

    • Polymer Name:Cyclic Olefin Copolymer (COC)
    • Processing Methods:Injection Molding
    Polyplastics Group Topas® 8007S-04Product DescriptionTOPAS 8007S-04 is a general purpose injection molding grade. It is a glass-clear amorphous polymer with outstanding moisture barrier, chemical resistance, high purity and a non-reactive surface making it an excellent choice for healthcare and other high-tech products. Lower leachables and extractables of TOPAS COC preserve content stability and quality. It is a non-polar substrate that does not promote adsorption, denaturation, aggregation, or precipitation like glass can. Analytical results are more accurate with TOPAS COC in contact with sensitive chemistries.Selected Applications Drug delivery Prefilled syringes, vials, cartridges Bottles and tubes Surgical instruments IV containers and components Labware Optics Electronics Food packaging Healthcare and food contact Leading Attributes Low leachables & extractables, low water transmission Non-ionic, does not promote adsorption like glass Minimally reactive Chemically resistant to alcohol, acetone, and acrylates Transparent, withstands EtO and gamma sterilization Temperature resistance, clarity and purity Clarity, low birefringence, low moisture sensitivity Low dielectric constant, thermoplastic Not manufactured with BPA, phthalates, or halogens Broad regulatory compliance Related Grades for Injection Molding, Healthcare, Optics and Diagnostics TOPAS 8007X10 - our highest ultraviolet (UV) transmission grade Topas® 8007S-04Topas® 8007S-04 is a Cyclic Olefin Copolymer (COC) product. It is available in Asia Pacific.Characteristics include: Flame Rated Copolymer

    Goodyear Rubber Company of So. California Silicone rubber is an elastomer different from other rubbers in that it has an inorganic backbone made of silicon and oxygen atoms. Organic rubbers have a carbon-carbon chain atomic structure. The outstanding physical property of silicone is its’ retention of flexibility and tensile strength at relatively high and low temperatures, from -150 F to 600 F. Silicones are very flexible due to large bond angles and bond lengths compared to basic organic polymers. Silicone rubber is a material of choice where retention of shape and mechanical strength are desired under heavy thermal stress or sub-zero temperatures. Silicone rubber is highly inert and does not react with most chemicals and due to its structural properties, it is widely used in aircraft engine parts, door and window sealing parts, healthcare and medical applications including implants.
