Anti-Scratch Additives For Plastics

Anti-scratch Additives for Plastics

08-Sep-16

Anti scratch additives not only reduce scratch width, depth and visibility but the highly stable additives offer no negative impact on parts including low visible bloom, low odor and maintained gloss. Introduced by Croda, the range offers products for a variety of polymers and applications from high gloss surfaces to transparent parts.
Croda launched their range of anti-scratch additives to meet the demand for improved quality of plastic parts in high end applications. Croda’s additives include high stability products that work from within the formulation to enhance plastics’ surface properties.
They can withstand challenging processing conditions and give long term in-use performance in the finished products. Additionally, their low usage levels do not cause any detrimental effect on mechanical properties.
The range includes Incroslip SL and IncroMold K for polypropylene impact copolymer and Incroslip G for polypropylene homopolymer applications.

Incroslip SL - Key Benefits

High and long lasting slip performance
Excellent organpleptics
High oxidative stability
Scratch and scuff protection
Low visible bloom
Low application and release torque
Food contact compliance

IncroMold K - Key Benefits

Developed specifically as an anti-scratch additive to reduce scratch visibility and whitening in PP impact copolymer.
IncroMold K is suitable for use at temperatures up to and above 280°C and is recommended for when reduced scratch visibility is required.

Incroslip G - Key Benefits

Shows excellent anti-scratch properties in PP homopolymer.
This product also has the added benefit of reducing mold release force, enabling molded parts to be removed from the mold easier.
This eliminates the need for silicone sprays and allows continuous production.

The range also includes products for transparent polymers including polycarbonate and PMMA. These polymers are tough and rigid polymers which can be used in automotive applications such as headlights and interior parts, however they are prone to scratching. Croda’s IncroMax range shows excellent anti-scratch performance in transparent polymers with no negative impact on clarity.
