Notes for oil injection of TPE/TPR toy products
Some toy products need to spray oil on TPE/TPR material. In fact, there will be special matters needing attention when spraying oil. Generally, the main component of paint is resin, whose function is to make pigment bond to the surface of adhesive parts. General TPE paint is used aromatic hydrocarbon and ketone - based.
Notes for TPE/TPR oil injection
First,Solvent reason
For general hard general materials such as ABS and HIPS, paint usually with a weak chemical performance of the solvent. In order to ensure that the rubber parts in the oil injection can still maintain a smooth surface without loss of physical strength.
On the other hand, the general plastic of general soft body, wait like PVC, match the solvent with stronger chemical property normally. Because soft plastic parts will have a certain degree of deformation and elongation, strong solvent can ensure that paint will adhere to the glue, even if the soft plastic deformation is not easy to come out.
TPE combines the characteristics of soft and hard adhesives. Injection of oil if the problem, often due to the choice of solvents, as a result of burning glue, deoiling.
