As a rule, the plastic materials regularly utilized in connectors are separated into two kinds: thermoplastics and thermosetting plastics. Thermoplastics incorporate polyamide, polycarbonate, polyvinyl chloride, ABS, polyurethane, polysulfone, polytetrafluoroethylene, polyethylene, polypropylene, polyphenylene oxide, polyester and PP. Thermosetting plastics incorporate phenolic sap, urinary formaldehyde, DAP and epoxy pitch. Coming up next is a short prologue to the exhibition of these materials:
(1) Polyvinyl-chloride (PVC), for the most part utilized for link coats, heat shrinkable cylinders, it has great physical properties, climate obstruction, low dampness ingestion, great expulsion forming, not reasonable for the shell it is clingy of. Warmth opposition 600C°.
(2) Nylon Polyamide (PA), smooth white, great sturdiness, wear obstruction, scentless, can bore, cut, plan, infusion shaping, great wet blanket opposition (KB600), dampness ingestion. Warmth obstruction 1050C°.
(3) Polycarbonate (PC), great wear opposition, great pliability, great protection execution, dimensional strength, helpless dissolvable obstruction, low water ingestion, regularly utilized in multi-position connectors, medium opposition Creep (KB125). Warmth opposition 1300C°.
(4) Polytetrafluoroethylene (PTFE), magnificent temperature obstruction, great synthetic and dissolvable opposition, climate opposition, phenomenal protection execution, hard to retain water, over the top expensive, and radiation safe. Warmth obstruction 2500C°.
(5) Epoxy (EP), epoxy gum is normally utilized for top notch printed circuit sheets, for LGH and ARINC, magnificent quality and durability, astounding grip to different materials, low Dielectric consistent and high withstand voltage, great mechanical strength, relating misfortune, heat obstruction 1100C°.
(6) Polyethylene (PE), amazing substance obstruction, great protection execution, less expensive, utilizing low-thickness polyethylene. Warmth opposition 800C°.
(7) Polypropylene (PP), light weight, less expensive, wear-safe, great building execution, not water-safe, utilized for little and ultra-little coaxial connectors. Warmth obstruction 900C°.
(8) Polyphenylenoxyde (PPO), great designing execution, great mechanical and electrical properties, helpless dissolvable opposition. Creep opposition (KB300), heat obstruction 1050C°.
(9) Polyester (PBT), this thermoplastic is progressively utilized, incredible compound and electrical properties, dimensional dependability, great pliancy, creep obstruction (KB250), heat opposition 1200C °.
(10) Phenolic (PE), phenolic pitch is made out of phenol and formaldehyde polycondensate, brilliant protection from load distortion, dimensional soundness in a wide temperature go, synthetic opposition, regular solvents and frail acids, admissible protection execution , Heat obstruction 1500C°.
(11) UeaFormaldehyde (MF), which is made out of melamine and formaldehyde polycondensate, high mechanical obstruction, low value, high wet blanket opposition (KB600), and numerous hues. Warmth obstruction 700C°.
(12) DAP Diallyphtalate (DAP), incredible dimensional security, temperature obstruction, brilliant dampness opposition, creep opposition (KB600), is the best plastic, normally blue, utilized for the most exceptional military Connector, the cost is extremely high. Warmth opposition 1800C°.
(13) Acrylonitrile/butadiene/styrene copolymer (ABS), this plastic is utilized as a substitute for nylon shell, great mechanical properties, heat obstruction and synthetic concoctions, simple handling, less expensive than nylon, creep opposition KB300) . Warmth opposition 600C°.
Also, there are dim or white polysulfone (PSU) and beige PEEK materials, which have fantastic mechanical properties and are appropriate for use in steam sanitization conditions.
