Additionally, plastic prefilled syringes can be color-coded for easy identification and customized to meet specific opacities in polypropylene (PP) resin, while laser marking additives can help create precise, solvent-free markings.  Formulated with pre-tested raw materials, this range of additives helps enhance the performance and functionality of plastics used in medical devices and pharmaceutical packaging and mitigate the risk of non-compliance.

We have modified the existing ASTM D903 method for plastics in order to evaluate the adhesion of soft TPEs onto rigid thermoplastic. ENGINEERING PLASTIC SUBTRATES There are a number of plastic substrates that are used for various consumer applications. A single TPE chemistry can not bond to all the rigid plastic substrates as evidenced by the surface energies demonstrated in Figure 1.

Rubber and Plastics Manufacturers industry average. While plastics provide tremendous benefits in packaging applications, there is also a responsibility to ensure plastic waste does not end up in the environment. That is why Avient joined the Alliance to End Plastic Waste.
