Another bothersome rheological characteristic of typical extrudable
fluoropolymer is a very pronounced "stick-slip" phenomenon typical for fluoropolymer melts in general.
A process is needed for obtaining fibers from high-modulus, extrudable
polyethylene by extrusion and stretching in state-of-the-art equipment.
They are being introduced to OEMs as a lower cost, easier-to-process, environmentally-safe, higher attenuation, higher shielding, more design flexible, injection moldable and extrudable
and co-injection/multi-shot capable replacements for silicones and lesser effective TPEs used for EMI shielding applications.
They are being replaced by injection moldable and extrudable
heat-conducting plastic compounds that provide lightweight cooling solutions.
For example, if the compound did not stick to the barrel of an extruder during processing, it would not be extrudable
BASF has developed a family of hard, extrudable
silicone was first commercialized in Europe but is now also available here.
Elastosil R 401/10 is said to be the world's first bubble-free extrudable
10 durometer A silicone.
HiTech Polymers reports that the resins are extrudable
, formable, moldable, grind-able, and foamable, permitting conversion into the form or application of a customer's choice.
Among them are the latest in the Maxelast family of SEBS-based TPEs from Polymax: Maxelast C Series of ultra clear TPEs for products ranging from soft-gel shoe insoles to health and sports equipment; extrudable
D series for cost-effective replacement of vulcanized rubber and EPDM; and Maxelast D extrudablc film series for gloves.
Cylinders from 2" (50 mm) to 100" (2,540 mm) can be covered with virtually any extrudable
elastomer or resin to any reasonable wall thickness amount at rates proportionate to the extruder outputs.
Applications for the injection moldable or extrudable
grades include medical and FDA tubing, food packaging, baby-bottle nipples and pacifiers, infant sipper cups, infant toys, seals, gaskets, and fluid delivery systems.
