Details of Polymethyl Methacrylate for your reference
Description
PMMA resin is a mature product that HY Corporation has accumulated more than 30 years of acrylic sheet manufacturing experience, introduced in US continual process, and used methyl methacrylate (MMA) as major raw material to develop successfully. It has excellent weather-resist and heat-resist character, and excellent transparency and gloss. Besides, it has stable physical, chemical, optical, and electrical, etc., characters. It may be widely applied on electronic panel, mechanical parts, watch and clock shell, motorcycle and automobile indicator, tele communication material, insulation parts and sun glasses, etc.
Application
1. Extruded sheets for signage, displays and building material
2. Automotive parts such as tail lamps, meter covers and sun visors
3. General sundries such as tableware, kitchenware, giftware and bathroom accessories
4. Optical lenses such as sunglasses, reading glasses and camera lenses
5. Light guide panels for LCD displays
6. Other applications such as mobile phone display panels, clock covers, lighting covers/accessories, optical fibres, toys, etc
