Additive Master Batch

GRP offers a portfolio of differentiated Specialty Additive Masterbatches for niche applications in the Packaging, Automotive and Industrial sectors.

Product Name : GRPpur
Product Model : GRPpur100P , GRPpur200E
Details : Ready-to-use thermoplastic purging compound specially developed to clean the barrel effectively during processing of various engineering as well as commodity plastics. It finds use in injection moulding, blow moulding, as well as in the extrusion process.
Product Name : GRPaid
Product Model : GRPaid700P, GRPaid800E
Details : Is a thermoplastic-based masterbatch being used as a mould release agent during injection moulding process of various Polymers. It facilitates easy ejection/removal of moulded articles from the mould without affecting the properties of the articles.

GRPpur100P

Product : Purging/Cleaning compound
Grade : GRPpur100P
Suitable for : Polyolefins colour/ material changeovers
Applications :
