tpe sex dolls cracking cause
The causes of tpe sex dolls cracking may involve many aspects, including material aging, stress concentration, improper processing technology, etc. Here are some specific causes that may cause tpe sex dolls to crack and their corresponding solutions:
material aging : TPE material in long-term use or exposure to harsh environment, may be aging due to ultraviolet light, light, ozone and other effects, resulting in material brittleness, resulting in cracking. Solutions include replacing other materials that are resistant to UV corrosion, such as TPV. 12
stress concentration : unreasonable product design or excessive stretching and extrusion in the process of use, easy to lead to stress concentration, resulting in cracking. Solutions include optimizing product design, avoiding overly complex structural design and uneven thickness, and designing arc structures as far as possible to reduce stress defects. 12
processing problem : Improper processing technology, such as excessive heating, rapid cooling, etc., may cause damage to the TPE material and lead to cracking. The solution includes improving the processing technology, reasonably setting the injection molding process parameters, and ensuring that the material is fully plasticized during the processing. 25
Material quality issues : Low quality TPE materials may contain impurities or defects that can easily lead to cracking. The solution includes optimizing material selection, selecting TPE material with stable quality and good compatibility with substrate.
solvent corrosion : Some glues and paints have strong corrosion, if not handled properly, may lead to cracks in TPE products. Solutions include paying attention to the amount of glue and paint used, and avoiding excessive use in local parts of the product. 1
temperature effect : When the temperature is low, the tensile property of TPE material will become worse, resulting in product fracture. Solutions include the use of base materials that maintain tensile properties at low temperatures. 6
Formula problem : poor aging resistance of TPE blending system may lead to aging cracking of soft TPE products. The countermeasures include improving the aging resistance of the blending system and adding aging resistance additives. 7
In addition, tpe sex dolls cracking may also be due to low molecular weight of the substrate, high temperature during molding, insufficient plasticization and other reasons. The solution includes the selection of substrate with higher molecular weight and strict control of molding temperature. 8
