The Zero Degree Chamber is specially used to condition the R-PVC pipes at 0 Deg. C. For impact testing as per IS 4985 standard.A true material comparison is possible only when property values are determined by identical test methods under identical conditons. Generally speaking, physical and mechanical properties of plastics and electrical insulating material are affected by temperature and humidity. Plastic materials tested above room temperature will yield relatively higher impact strength and lower tensile strength and modulus. Obviously, in order to make reliable comparisons of different materials and test results obtained by different laboratories, it is necessary to establish standard conditions of temperature and humidity for testing.

ApplicationThis Hopper Loader is widely applied for automatic conveying powder or powder/granules mixing in the industries such as plastic, rubber, chemical, color, food, medicine etc. The filter property is excellent even for the mixing material of CaCO3(Calcium Carbonate) and PVC in which the contant of CaCO3 is less than 50 %.

The UNIVERSAL TENSILE TESTER is used for determining the ability of the material to withstand forces that tend to pull it apart & to determine to what extent the material stretches before breaking.Different type of plastic materials are often compared on the basis of TENSILE, FLEXURAL STRENGTH, ELONGATION, & TENSILE MODULUS DATA. Many plastics are very sensitive to the rate of straining and environmental conditions. The tensile property data are more useful in preferential selection of a particular type of plastic from a large group of plastic materials.Tests for tensile strength (stress at fracture of the specimen) and elongation (extension of material under load of plastics. The first provides a measure of the breaking strength of the material but is radically affected by the rate of loading and the ambient temperatuere. Tensile strength in kgf/cm sq. = load (kgf) / a x b (cm sq.) Elongation % = (L2-L1) x 100/L1. Standard test methods : BS 2782 method 301, ASTM D 638, ISO R527.
