What are the characteristics of acrylic?

Acrylic is a generic term for acrylic chemicals. In the field of plastics, acrylic refers to polymethyl methacrylate, or PMMA, which is a thermoplastic engineering plastic with excellent comprehensive properties. The most prominent feature is crystal-like transparency, with a light transmittance of 92%, which is the highest among plastic materials. Acrylic is also the least sensitive to ultraviolet (UV) of all plastics. Acrylic is also not easy to oxidize and has strong weather resistance. Acrylic boards are divided into cast boards and extruded boards according to the production process; according to product performance, they can be divided into transparent boards (including dyed transparent boards) and colored boards (including black and white and color boards), ordinary boards and special boards, such as high resistance Impact board, frosted board, metal effect board, high wear-resistant board, flame retardant board, light guide board, etc. Acrylic sheet has the characteristics of light transmission, durability, changeable shape, and diversified colors and surface effects.

testing regulations;
⑴ The acrylic sheet is coated on both sides. At the time of acceptance, the uncovered film will be randomly inspected.
⑵ Complete inspection of acrylic sheets other than the uncovered film sampling inspection, mainly to check whether the outer film is damaged, and perform partial uncovering inspection on the damaged film.

Quality inspection standards;
⑴ Residual silicon glass, silicon glass cracks, silver streaks, cracks, surface shrinkage marks and obvious surface scratches are not allowed on the surface;
⑵ Allow inconspicuous fine scratches and dispersive foreign impurities;
⑶ No more than 2 bubbles with a diameter of less than 2mm in the whole plate;
⑷ Length and width dimension deviation ≤±2．0㎜ (length and width dimensions are subject to the boundary of the available plate)
⑸ When the thickness is ≤2.0mm, the deviation is ≤±0.2mm
⑹ When the thickness is 4.0mm, the deviation is ≤±0.2mm
