【簡單介紹】
【詳細說明】
SABIC PEI Extem VH1003M產品描述:
Transparent, Thermoplastic Polyimide (TPI) resin with a glass transition temperature (Tg) of 247C. Internal mold release. This product has thinwall FR capability and has a UL94 V0 listing. This material is RoHS compliant and also halogen free according VDE/DIN 472 part 815. Resin is a Dual-use item and is subject to export control restrictions under both U.S. 15 CFR 774 and Annex I of Reg. (EC) 428/2009 as ECCN 1C008. Diversion contrary to law is prohibited.LONG-TERM HEAT RESISTANCE
Excellent stability of physical and mechanical properties at elevated temperatures thanks to high glass transition temperature of up to 311°C. Available with relative thermal indices (RTI) up to 230°C (preliminary).
STRENGTH AND STIFFNESS
Outstanding strength, stiffness and creep resistance with predictable performance up to 230 °C (preliminary). Tensile strength of typical die cast aluminum at 200 °C. Extem XH resin is approximay 50% stronger at 170 °C than Ultem. Unfilled, transparent grades are equal in strength to other thermoplastics with opacifying fillers。
DIMENSIONAL STABILITY
Among the most dimensionally stable thermoplastics available, offering predictability over a broader temperature range exceeding 200 °C. Filled grades offer exceptionally high-tolerance dimensional capabilities.
ENVIRONMENTAL STRESS &CRACKING RESISTANCE
Unlike most other amorphous thermoplastics, Extem resins retain strength and resist stress cracking when exposed to automotive and aircraft fluids, aliphatic hydrocarbons, alcohols, acids as well as chlorinated solvents such as methylene chloride.
FLAMMABILITY,SMOKE GENERATION AND TOXICITY
Inherently flame-retardant without the use of halogenated additives, which can pose an environmental risk. Extem resin is exceptionally difficult to ignite, with a limiting oxygen index (LOI) of 45% (preliminary). Extem resin is expected to retain the UL performance and flame, smoke and toxicity strengths of Ultem resin.
PROCESSABILITY
Extem resin can be processed in conventional drying and injection molding or extrusion equipment capable of running Ultem* resin and other high heat thermoplastics. Extem can be film and profile extruded, thermoformed, extrusion blow molded, extruded into stock shapes, and injection molded. Flowability can be tailored to meet customer applications through product and processing design and flows similar to Ultem resins.
