Acrylic craft characteristics
1. Polymethyl methacrylate containing polarity methyl, has the obvious hygroscopicity, bibulous rate is in commonly 0. 3% - 0. Will acrylic should be dry before 4%, molding, drying conditions is 80 ℃ Under the 85 ℃ drying - 4 5 h。 2. Polymethyl methacrylate in processing the temperature range of effective apparent characteristics of non-newtonian fluid, the melt viscosity with the increase of shear rate will be significantly lower, the melt viscosity are also sensitive to changes in temperature. So for polymethyl methacrylate processing, improve the molding pressure and temperature can significantly reduce the melt viscosity, obtain good liquidity. 3. Poly (methyl methacrylate to flow the temperature about 160 ℃, began to decompose temperature higher than 270 ℃, has a wide processing temperature range. 4. Polymethyl methacrylate high melt viscosity, cooling rate and faster, the products are prone to stress, thus forming the strict control of process conditions, after molding, products also need the reprocessing. 5. Polymethyl methacrylate is amorphous polymers, shrinkage rate and its variation range are smaller, generally about 0. 5% - 0. 8%, which is beneficial to high dimension precision plastic forming parts. 6. Polymethyl methacrylate cutting performance is good, the material can be easily machined into the size of the various requirements.
