Wood Pattern Acrylic Sheet

Wood Pattern Acrylic Sheet

The sheet's hardness directly influences how much it contracts, bends, and deforms, as well as how much the surface breaks during processing. The typical hardness of acrylic sheet is 8 or 9, making it one of the difficult indications to use to gauge the quality of acrylic sheet.

What are the process characteristics of acrylic sheet?

1. Hardness directly affects whether the sheet shrinks, bends and deforms, and whether the surface cracks during processing. The hardness of acrylic sheet is one of the hard indicators to measure the quality of acrylic sheet and the average hardness is 8 degrees or 9 degrees.

2. Thickness (Acrylic Tolerance) The thickness of acrylic sheet has acrylic tolerance, so the control of acrylic tolerance is an important manifestation of quality management and production technology. The production of acrylic has the tolerance requirements of the international standard GB7134 cast plate: the tolerance of 3mm thick acrylic plate is ± (0.4mm)

3. The transparency of acrylic sheet, raw material selection, advanced formula follow-up and modern production technology ensure that the sheet has good transparency.

4. The acrylic sheet has effective and obvious non-Newtonian fluid characteristics within the forming temperature range. As the shear rate increases, the melt viscosity decreases significantly, and the melt viscosity is also very sensitive to temperature changes. Therefore, for the molding process of acrylic sheet, increasing the molding pressure and temperature can significantly reduce the melt viscosity and obtain better fluidity. The acrylic sheet begins to flow at around 160°C, and begins to decompose above 270°C, and the processing temperature range is wide. Acrylic sheet has high melt viscosity and fast cooling speed, and the product is prone to internal stress. Therefore, the process conditions are strictly controlled during the molding process, and post-processing is also required after the product is formed. Acrylic sheet is an amorphous polymer, and its shrinkage rate and variation range are small, generally around 0.5%-0.8%, which is conducive to molding plastic parts with high dimensional accuracy. Acrylic sheets have good cutting properties and their contours can be easily machined to various desired sizes.

5. It has crystal transparency, the transmittance is greater than 92%, the light is soft, the vision is clear, and the acrylic color plate has a good color rendering effect. Acrylic sheet has excellent weather resistance, high surface hardness and gloss and good high temperature performance. Acrylic sheets have good processability and can be thermoformed or machined. The transmittance of transparent acrylic sheet is higher than that of glass, but its density is only half of that of glass. Also, it is not as fragile as glass. Even if it is damaged, it will not form sharp shards like glass. The wear resistance of acrylic sheet is close to that of aluminum, with good stability and corrosion resistance of various chemicals. Acrylic sheet has good printability and sprayability. Use proper printing and spraying processes.

During processing, since the cooling rate of the acrylic sheet is very fast, and it takes more than ten seconds to set the shape at normal temperature, those who want to customize the shape need to strictly control the temperature.
