TPE, TPR materials in the processing into products, sometimes there will be products ooze, spit oil, oil precipitation (surface sticky, or even directly wipe out a layer of oil to the hands) situation. This situation, according to the different material blending system, there may be two different factors, the plastic Bo is now briefly analyzed as follows.

  1. TPE, TPR blending system (lower hardness 0 ~ 20A) oil locking and oil absorption problems

  General SEBS-based TPE, TPR than the SBS-based TPR has a better oil absorption (oil absorption rate). As for SEBS, the oil absorption and oil locking properties of SEBS grades vary with different physical properties (such as butadiene content and different molecular chain structures). Choosing SEBS, especially the SEBS grade with good oil locking property, and choosing the right type of operating oil will reduce the problem of oil spitting on the surface of TPE materials, especially the lower hardness TPE materials (usually the lower hardness TPE materials will be matched with more proportion of operating oil, and the chance of oil precipitation is higher).

  2. TPE blending system (higher hardness 90A or more) oil precipitation

  Higher hardness of TPE, especially the SEBS base system of TPE, because the rubber SEBS content in the blending system is relatively reduced, which leads to TPE blending material oil absorption is small, if the blending system to add oil more than a certain limit, it is easy to precipitate out. For some larger size, thinner high hardness TPE products, the possibility of this surface oil spitting problem will be greater.

  In short, TPE, TPR products surface oil seepage, oil spitting, is basically a TPE, TPR material problems, and the user's production and processing process is not related. In terms of materials, there are three factors, one is the SBS, SEBS substrate and characteristics; second is the type of operating oil and characteristics; third is the TPE, TPR granulation process process control.

  If the surface of the TPE products spitting oil, there is basically no effective remedial treatment. If you happen to encounter the problem of oil spitting on the surface of TPE processing, you can consult our company in order to provide material solutions to the problem of oil spitting on the surface of TPE products.
