The quality of a silicone rubber product, in addition to the appearance and size that we are familiar with, also has a very important indicator that is whether the product's physical properties meet the design requirements. Are some basic routine physical property tests for your silicone rubber products?
In fact, the physical properties of silicone rubber products are largely determined by the material of the product. When a product is manufactured, the physical properties of the product itself are basically set, so many times we will The raw materials of the products are subjected to a standard test piece for relevant testing.The first aging resistance test, aging test is divided into temperature aging, sunlight aging, load aging and so on. , 工业的一般用 70 度 ,70 个小时 , 温度为分为几个等级通常有 70 摄氏度， 100 摄氏度， 125 摄氏度等检测时间均为 70 个小时。 For silicone rubber products, we use temperature aging the most. It is carried out in an aging test box . High temperature aging is generally divided into several levels . Generally, it is 70 degrees and 70 hours in industry. The detection time of Celsius and 125 Celsius is 70 hours.
The second tensile test is well understood, that is, under the same conditions, the maximum tensile force per unit area of the material can withstand without breaking, which is usually tested on a tensile machine.
The third extension performance test refers to what we usually call the tensile elongation, which is the percentage of the maximum tensile length of the material under the normal temperature environment. The fourth test for tear resistance. This test is similar to the tensile test, except that the direction of the force during the test is different, and it is in a fan direction.
10mm 的硬度块用硬度计手动进行测量。 The fifth hardness test is the most basic and relatively simple test for silicone rubber products. We usually make the material into a hardness block with a thickness of 10mm and manually measure it with a hardness tester. Of course, there are still many people testing silicone rubber products, such as abrasion resistance testing, oil resistance testing, acetic acid testing, etc. These tests are more common tests in our silicone rubber industry. In addition, the testing standards in different regions will be different. for reference.
