 The Advantages Of Our PMMA Sheet
1. Features
Features:
1) Excellent property / price ratio: Think sponsor carries out acrylic sheet character in the same business firstly. Customers can buy the best products with the lowest price under the same level of fine quality
2) Hardness: hardness is the key step for controlling the quality of products and it is one of the technique and skills of cast acrylic sheet representing product. It can explain the strength of raw material "MMA" and the resistance of acrylic sheet at high temperature, which directly effects the acrylic sheet whether it will be contracted or warped, and shows the surface will occur crack or not when tooling. According to Rockwell Harness, usually the standard of hardness is substandard when below 86°C. Think cast acrylic sheet holds the most firm point
among the same domestic products at present. Average of Rockwell harness is 89°C
3) Thickness: thickness is so important that it represents quality management and product technique. During producing process, we spent most time and energy in controlling the thickness. Thickness within ±0.2mm of Ritian excellent sheet, let us keep ahead among the main domestic manufacturers
4) Transparency: with strict material choosing, advanced mixture, modern produce technique manufacture which makes sure that Think sheet's excellent transparency and pure white degree. It will bright and transparent after fire and cloth polishing
5) Variety: Think cooperates with some painting firms all over the world. Apart from general purpose clear sheet, color sheet and various special sheet, such as clothes bed sheet, and marble sheet. Gold shallot flower sheet, cast and extrusion, various flower types. Let us create a wonderful world of acrylic sheet product together
6) Technology: you can choose the thickness of acrylic sheet from 1.5mm to 50mm freely. We will give consulting and technical instruction for free during using and producing process of acrylic sheet
7) Inspection: Think has an inspection team full of training, responsible and meticulous spirit, according to IS09002 quality system standard, follow production, from raw material choosing, producing, accurate trimming, to strictly protection
8) Service: customer's benefit is ranging the highest place for us, who has been insisting: people is base, business is resource, quality is response. Service follow roduct from factory to client, establish customer data file and deal with customer questions in time. We continue to improve the service attitude and working style and let
client satisfy our product and service when they purchase it.

| Acrylic Introduction
1. What is PMMA?
PMMA is a glassy polymer with an amorphous structure. It has a density of 1.19 g/cm3 and has very low water absorption. The refractive index ranges from 1.49 to 1.51 depending on the type. It is one of the earliest polymers and is well known around the world by a variety of trade names Lucite, Oroglas, Perspex and Plexiglas which vary with the country you are in. The original PMMA was seen as a replacement or glass in a variety of applications and is currently used extensively in glazing applications. The material is one of the hardest polymers, rigid, glass-clear with glossy finish and good weather resistance.
2. The history of PMMA
Polymethyl methacrylate, more commonly called acrylic or ‘Perspex’, was first produced commercially in the UK in 1934. Its shatter-resistant properties were soon in vast demand for aircraft canopies and all kinds of protective screens.
3. Typical Applications
Optics: Dust covers for hi-fi equipment, sunglasses, watch glasses, lenses, magnifying glasses
Vehicles: Rear lights, indicators, tachometer covers, warning triangles
Electrical engineering: Lamp covers, switch parts, dials, control buttons
Office equipment: Writing and drawing instruments, pens
Medicine: Packaging for tablets, pills, capsules, suppositories, urine containers, sterilisable equipment.
Others: Leaflet dispensers, shatter-resistant glazing, shower cubicles, transparent pipelines, illuminated signs, toys.
