vespel® sf foam products offer performance at extreme temperatures-j9九游会老哥论坛

solution

• vespel^® sf is a unique open-cell high performance custom densified polyimide foam which has been produced at varying densities ranging from approximately 0.16–0.56 g/cc (10–35 lb/ft3) to suit the most demanding aerospace applications. (figure 4)
• customizable vespel^® sf densification allows for “tailoring” of mechanical properties to meet appropriate structural application needs. (figure 3) three standard grades (sf-0920, sp-0930, sf-0940) are available with respective datasheets.
• vespel^® sf can be pre-formed and machined into complex geometries to suit varying customer requirements. (figures 1 and 2)
• vespel^® sf is a durable material with a high degree of chemical stability as well as thermal and acoustic insulation.
• vespel^® sf offers high temperature continuous use at 300^°c (572^°f) with the added benefits of being flame resistant as well as safe to handle when exposed to open flames with no off gas or release of toxic fumes.
• vespel^® sf can be easily bonded to various mating surfaces thus making them suitable for field repairs.

features and benefits

• sealing properties
  vespel^® sf seals offer a unique balance of properties including durability, high temperature resistance, low cte, abradable properties, and low weight (pcf) without compromising structural integrity making it a material of choice when it comes to sealing applications.
• tensile strength
  ultimate tensile strength varying from approximately 425 to over 26,000 kpa (61–3,700 psi) depending on the design density.
• safety and environmental stewardship
  fire resistant by design, vespel^® sf polyimide foam emits virtually no off gas and does not release toxic fumes when exposed to open flames. its non-fibrous composition promotes safe handling during processing and final assembly.
• design flexibility
  vespel^® sf can be molded and machined to match unique geometries of both common and complex designs. parts can be easily bonded at initial assembly or in the field. (figures 1 and 2)
• improves efficiency by reducing fuel consumption and increasing payload capacity
  vespel^® sf polyimide foam can be manufactured to meet density requirements in the range of approximately 0.16–0.56 g/cc (10–35 lb/ft3).
• solving a variety of problems 
  from abradable seals, stator vane seals, variable bushing packing, and nacelle insulation to composite paneling in structural applications, the versatility and durability of vespel^® sf products allows you to think out of the box to solve an array of problems where temperature resistance, weight, dampening, or sealing are of concern.
