Toughness means that the object is soft and not easy to break. The toughness of rubber material is excellent. TPE, also known as synthetic rubber, has the elasticity of traditional cross-linked vulcanized rubber and the workability of common plastics.
1. Material mixing system
TPE is a blend compound. Polymer rubber base material, TPE material toughness, stone powder filling less material, toughness is good.
2, forming temperature
Plasticization degree is an important factor affecting the toughness of TPE materials. If the molding temperature is not enough, then the plasticization of TPE material is not good, and its toughness will decrease. For TPE material molding temperature, different mixes, brand manufacturers, suggested parameters, please consult TPE material manufacturers.
3, the proportion of water mouth material added
TPE is a thermoplastic material that can be reused. However, with the increase of material use times, the physical properties of the nozzle material will decline. In general, it is recommended that the proportion of nozzle material in the forming process not exceed 25%. Too much water material will greatly reduce the toughness of TPE material.
4, whether the material aging photooxidation
If the material due to contact with ozone, ultraviolet and other media, physical properties will decline. When selecting materials, it is necessary to confirm the requirements of materials with the upstream and downstream of the industrial chain in advance, and then select suitable TPE brand.
5. Structural defects of products made of TPE materials
Check whether there are welding marks and stress concentration in the product, such as the corner without R Angle, the water mouth is just in the stress position, etc. TPE material manufacturers remind you that the existence of these factors will lead to the material toughness decline, easy to break.
