Synthetic rubber is a highly elastic polymer made by artificial synthesis. Also known as synthetic
elastomer, is one of the three major synthetic materials,Special synthetic rubber also has different specific properties,these properties are often better than natural rubber and other varieties of synthetic rubber.
Most synthetic rubber and natural rubber, mainly used in the manufacture of automobile tires,
tape, hose, rubber shoes, cables, sealing products, medical rubber products, adhesives and latex products.
Selection guide
The physical and chemical properties of rubber to a large extent determine the final use performance
and life of processed material products, so the selectionof rubber should not be limited to the existing
raw materials, but must be from the investigation of human hands, in a variety of rubber repeatedly
screened toachieve the desired purpose.
When selecting raw rubber varieties, it is usually necessary to pay attention to master and comply with
the following principles:
1. Main performance. The rubber should be selected according to the required performance, such as
tire fatigue heat resistance and wear resistance; Air permeabilitresistance of the inner tube; Oil resistance
and compression resistance of seals; Corrosion resistance of hose and container, insulation performance of
electrical materials, etc.
2. Other consideration of performance. In the selection of raw rubber, but also take into account
other properties.
a. Self-weight and load condition requirements;Mechanical strength, rigidity, creep resistance.
b. Environmental requirements: heat resistance, cold resistance, water resistance, oil resistance
and chemicalresistance.
c. Other additional conditions: transparent, bright, light, heat insulation, etc.
3. Durability. The selection of raw rubber should consider its durability, according to the requirements
of the conditions of use, there are wear, cracks, sticky,hardening and other aspects; According to
the requirements of the surrounding medium, heat sources, sunlight, ozone, humidity, mechanical
forced stressdeformation, etc., should be considered.
4. Processing performance
a. The difficulty of mixing rubber with ingredients.
b. The range of molding methods: paste molding, extrusion rolling molding, compression molding,
injection molding.
c. vulcanization adaptation range: high temperature and low temperature, pressure without pressure,
air, steam, hot oil, electric heating.
d. Secondary processing methods of product materials: cutting, opening, hot processing, bonding,
electroplating, printing, etc.
5. Security. Such as fire resistance, electric resistance, etc., the risk of transportation and storage.
6. Economy. It is necessary to consider the comprehensive economic performance of the product
cost of the processing fee of the material, the production cost of maintenance and material replacement,
other substitution fees and surcharges.
7. Social and environmental responsibility. It is necessary to ensure that raw rubber is non-toxic and polluting
when used, and consider its impact on human health and waste disposal.
