The Material Of The Keyboard Shell Is More

NCK Technology Co.,Ltd | Updated: Aug 02, 2017

Keyboard shell common material mainly has hips, PC, ABS, ABS+PC, PBT, Pom. Let's take a look at these 6 types of material.

Hips is one of the cheapest engineering plastics, with ABS, ABS, PC compared to the gloss of the material is poor, comprehensive performance is also relatively poor. Hips are modified by PS Jadin, because the impact strength of PS is very low, made the product is very crisp, and Butadiene's toughness is very good, after adding butadiene can make PS impact performance to improve $number times. Keyboard Housing Although hips impact strength is much higher than the impact of PS, but its comprehensive performance is not as good as ABS, ABS and so on. Keyboard Housing Hips impact performance in engineering plastics is relatively low.

Introduction to PC

PC Polycarbonate (polycarbonate) abbreviation for PC is a colorless and transparent thermoplastic material.

Polycarbonate is a common material. Keyboard Housing Due to its colorless transparent and excellent impact resistance, daily common applications are CDs, eye patches, water bottles, bulletproof glass, goggles, bank bullet-proof glass, headlights and so on. Polycarbonate is also used to make helmet masks for astronauts on the moon.

ABS Introduction

Chemical name: acrylonitrile-butadiene-styrene copolymer, English name: acrylonitrile butadiene styrene (ABS) ABS resin is currently the largest production, the most widely used polymers, both toughness, hard, Keyboard Housing rigid phase equilibrium excellent mechanical properties


1, Keyboard Housing the comprehensive performance is good, the impact strength is high, the chemical stability, the electrical property is good.

2, with 372 plexiglass of good fusion, made of two-color plastic parts, and can be surface chrome, spray painting treatment.

3, with high impact, high heat resistance, flame retardant, enhanced, transparent and so on.

4, liquidity than hips almost, than PMMA, PC and so on, good flexibility.

The disadvantage of ABS engineering Plastics: Thermal deformation temperature is low, Keyboard Housing combustible and weathering resistance is poor.

Use: Suitable for making general mechanical parts, antifriction wear-resisting parts, transmission parts and telecommunication parts.

ABS+PC profile

Commonly known as ABS plus poly carbon. It is one of the few kinds of materials which may be used in China, and it can not spontaneously combust, when the fire burns, Keyboard Housing the surface has the same small particles precipitated as carbon-burning, and the black is lower than ABS, which is common in electrical components, mechanical parts, etc.

About Us

Poly (butyl terephthalate), English name Polybutylece terephthalate (PBT), belongs to Polyester series, is from 1.4-butadiene alcohol (1.4-butylene glycol) and terephthalic acid (PTA) or terephthalic acid ester (DMT) poly condensation, and through the mixing process made of milky translucent to opaque, Keyboard Housing crystalline thermoplastic polyester resin. Together with pet collectively referred to as thermoplastic polyester, or saturated polyester.

PBT can also be called thermoplastic polyester plastic, for the use of different processing industry, the general number will add additives, or mixed with other plastics, with the addition of different proportions, can produce different specifications of the product. Because PBT has heat resistance, weatherability, drug resistance, Keyboard Housing good electrical properties, water absorption, gloss, and widely used in electronic appliances, automotive parts, machinery, household supplies, and PBT products and PPE, PC, POM, PA, etc. are known as the five major pan-use engineering plastics.

About POM

Pom is also known as poly-oxidized sub-methyl, English name Polyxymethylene (for short). Milky opaque crystalline polymers, density 1.42g/cm3, melting point 175 ℃, decomposition temperature 235~240℃ pom plastic is a fine resin variety developed after nylon, with excellent comprehensive performance.

ABS materials are most common, plasticity is very good, suitable for the production of high-precision parts, such as cherry Switch itself (except the cross column is a special low friction coefficient material), two-color key cap, suitable for low-cost high-volume production; PBT materials are not commonly used, because of high prices, but excellent physical and chemical properties, the biggest feature is wear-resistant, good flexibility, usually used to make toothbrushes brush hair, used in the key cap is more luxurious. The key cap of the POM has been seen cherry used, Keyboard Housing and POM in China is generally kindly called him race steel, the meaning is comparable to steel, he certainly does not have the steel performance good, but, in the special occasion, his superiority manifests, ultra high hardness, ultra low damp, excellent heat resistance, outstanding corrosion resistance, outstanding abrasion resistance.

Conventional keyboards have both mechanical and capacitive keys. There is also a keypad in the IPC keyboard that touches a thin film button--only for special occasions. Keyboard Housing Mechanical keyboard is the first to be used in the structure, generally similar to the principle of metal contact switch to contact or disconnect, mechanical-type key advantages are long life, long time to use the same feeling unchanged, and the key touch is very good. Mechanical cherry and Alps have long been the main manufacturers.
