  2. FFKM - Wikipedia

    en.wikipedia.org/wiki/FFKM

    Certain grades have a maximum continuous service temperature of 327 °C (621 °F). They are commonly used to make O-rings and gaskets that are used in applications that involve contact with hydrocarbons or highly corrosive fluids, or when a wide range of temperatures is encountered.

  3. High-performance plastics - Wikipedia

    en.wikipedia.org/wiki/High-performance_plastics

    There are many synonyms for the term high-performance plastics, such as: high temperature plastics, high-performance polymers, high performance thermoplastics or high-tech plastics. The name high temperature plastics is in use due to their continuous service temperature (CST), which is always higher than 150 °C by definition (although this is ...

  4. Thermoforming - Wikipedia

    en.wikipedia.org/wiki/Thermoforming

    In the most common method of high-volume, continuous thermoforming of thin-gauge products, plastic sheet is fed from a roll or from an extruder into a set of indexing chains that incorporate pins, or spikes, that pierce the sheet and transport it through an oven for heating to forming temperature. The heated sheet then indexes into a form ...

  5. Plastic extrusion - Wikipedia

    en.wikipedia.org/wiki/Plastic_extrusion

    Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping , fencing, deck railings , window frames , plastic films and sheeting, thermoplastic coatings, and wire insulation.

  6. Die forming (plastics) - Wikipedia

    en.wikipedia.org/wiki/Die_Forming_(Plastics)

    For products such as plastic sheets or films, cooling is achieved by pulling through a set of cooling rolls (also known as calender or chill rolls), usually 3 or 4 in number. In sheet extrusion, these rolls not only deliver the necessary cooling but also help determine sheet thickness and surface texture (in case of structured rolls; i.e ...

  7. Polypropylene - Wikipedia

    en.wikipedia.org/wiki/Polypropylene

    Polypropylene is most commonly used for plastic moldings, wherein it is injected into a mold while molten, forming complex shapes at relatively low cost and high volume; examples include bottle tops, bottles, and fittings. It can also be produced in sheet form, widely used for the production of stationery folders, packaging, and storage boxes.

  8. Polyimide - Wikipedia

    en.wikipedia.org/wiki/Polyimide

    These properties are maintained during continuous use to temperatures of up to 232 °C (450 °F) and for short excursions, as high as 704 °C (1,299 °F). [14] Molded polyimide parts and laminates have very good heat resistance. Normal operating temperatures for such parts and laminates range from cryogenic to those exceeding 260 °C (500 °F).

  9. Thermoplastic - Wikipedia

    en.wikipedia.org/wiki/Thermoplastic

    A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. [ 1 ] [ 2 ] Most thermoplastics have a high molecular weight .
