Croda at K 2016: To Exhibit Anti-scratch Additives for Plastics

Published on 2016-09-06. Author : SpecialChem

COWICK HALL, UK -- Croda will exhibit new range of anti-scratch additives at K 2016 in Dusseldorf, Germany and will be offering live demonstrations on the stand. These 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.

The range offers products for a variety of polymers and applications from high gloss surfaces to transparent parts. Technical experts will be present in Hall 7 stand C22 throughout the show to demonstrate how the range can reduce scratching using portable scratch testing equipment.

Additives to Enhance Plastics’ Surface Properties

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

Crosshatch scratch testing on automotive polymer
with and without Croda's anti-scratch additives.
  • 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.

Products for Transparent Polymers

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.

Technical Expertise

Applications Team Leader, Martin Read says “We have undertaken a significant project in the area of anti-scratch so that we are able to advise our customers which product and addition level will give optimum performance in their formulations. We are pursuing this work and would like to engage further with our customers to continue this process and meet future needs in the area of anti-scratch for a wide range of plastics.”

During the K show, Croda’s technical experts will be using scratch testing equipment to demonstrate how scratch visibility is reduced in a variety of polymers by the addition of small amounts of their specialty additives. Experts will then be able to work with customers and discuss specific projects.

Croda will co-exhibit with the Coatings & Polymers division who will be showcasing their range of bio-based building blocks and specialty additives. These sustainable and durable solutions bring benefits such as flexibility, water resistance, impact strength and color stability to high performance engineering plastics, elastomers and foams. Croda will be located in Hall 7 Stand C22.
