Ampacet Expands Anti-Scratch Additives Line

The new ScratchShield masterbatch additives prevent the appearance of scuffs and scratches in preforms, bottles, and a range of PET packaging without the need to apply a surface coating. 

Masterbatch supplier Ampacet has added two new additives to its ScratchShield product line to help protect plastic products from scratches and abrasion without affecting the resin’s gloss or mechanical properties.

The new ScratchShield masterbatch additives prevent the appearance of scuffs and scratches in preforms, bottles, and a range of PET packaging without the need to apply a surface coating. These additives also significantly improve the demolding of preforms while offering protection from guide rails and conveyor systems during the manufacturing process, said Ampacet 

Converters also benefit from scrap reduction, since ScratchShield minimizes the need to regrind scratched bottles and conduct cleanup associated with lubricant sprays. 

ScratchShield PET 7000076-E is designed for blow-molding processes. The additive restructures the surface of PET plastics, preventing crack propagation to limit whitening and hazing effects caused by abrasion. PET’s coefficient of friction also is significantly reduced during preform production, blow molding, handling, and transport, according to Ampacet. The additive significantly improves scratch and scuff resistance of preforms during conveyor belt handling.

ScratchShield 7000109-N is designed for use in translucent color and opaque blow-molded bottles. The additive reduces the occurrence and severity of scuffs and scratches both at the preform stage and in blown bottles, eliminating the need for atomized sprays.

In laboratory tests, Ampacet said that ScratchShield dramatically reduced scuffs at load forces up to 100 N; at forces lower than 25 N, scuffs were virtually eliminated in bottle-to-bottle tests. Scuff visibility tests showed significant resistance to scuffing when PET bottles with ScratchShield were compared to PET bottles with no additives, according to Ampacet.

ScratchShield 7000109-N is suited for applications such as alcoholic beverages (with a low alcohol content), automotive products, cleaning products, lotions, juices and soft drinks, pet-care products, and water cooler bottles.

The new additives join existing products in the ScratchShield family that enhance PP, ABS, PET, PE, clear polystyrene, and HDPE materials.
