Acrylic bottle is a new type of plastic container. Compared with other glass containers and metal containers, it has better product advantages. In terms of physical properties, acrylic bottles have the following characteristics.
One: mechanical properties
The mechanical properties of acrylic bottles include tensile strength, tensile modulus, elongation at break, flexural strength, flexural modulus, impact strength, Rockwell hardness, compressive strength, low temperature compressive strength, cutting strength, etc. These properties constitute the test methods for these mechanical properties that have been tested using ASTM techniques and D790, D785 techniques.
Two: Optical properties
In terms of appearance, the acrylic bottle has good light transmittance, so under the irradiation of light, its viewing effect will be better. The optical characteristics of the acrylic bottle include light transmittance (required above 92.5%), yellowness Index, Optical Refractive Index and Solderability Test Values.
Three: thermal characteristics
Since the acrylic bottle needs to be formed in a high temperature environment above 170 degrees, because of its related thermal characteristics, there are mainly heat distortion temperature, Vickers softening temperature, linear thermal expansion rate, heat transfer rate, horizontal combustion value, and molding temperature. , recommended critical point combustion temperature, etc.
Four: electrical characteristics
The electrical characteristics of the acrylic bottle are composed of two major parts: arc resistance and dielectric strength. The arc resistance of the point is required to be greater than 600 volts, and the dielectric strength is required to reach more than 18.3 kV per millimeter.
Five: other features
In addition to these conventional physical properties, the specific gravity of the acrylic bottle is above 1.09, and the water absorption is generally required to be above 0.265%.
