materials | Colours & masterbatch Online colour store answers small needs
Teknor Apex’s Color Division is trying to make online shopping as easy for colour concentrates as it is for consumer items. It has opened an online shop where processors can meet their small order production needs by ordering stock colours in 2lb bags (the shop is only open to North American customers). The company’s Color Store enables a
processor to purchase bags of twelve standard colours for polyolefins and some polyamides using a credit card or PayPal.
While colours are shipped in 2lb bags, customers may purchase up to 20lb per colour at a time. There is no limit to the number of standard colours that can be purchased. All orders are shipped via UPS with
freight prepaid and Safety Data Sheet (SDS) included. Overnight delivery is available. Teknor Color expects its Color Store to be especially advantageous for proces- sors with small product runs. “Colour
include additives that increase the UV resistance of some polyesters. Also new is a range of multifunctional masterbatch-
es delivering both colour and additives, “allowing for shorter cycle times to be achieved, improved surface appearance of the final product, ease of mould release on large components and reduced waste.”

Increasing functionality with ETPs Albis Plastic has transferred various additive technolo- gies it uses in some of its Alcom compounds for lighting-related applications into Alperform master- batches, called Alperform Light Diffusion and Alperform Light Blocking. It says that, besides being highly cost efficient, Alperform PC LD (based on polycarbonate) offers users a great deal of flexibility to adjust light transmission and scattering directly during processing. Alperform ABS LB, meanwhile, offers significantly increased light reflection and improved opacity, making it ideal for highly reflective and light-blocking LED light housings and reflectors.
suppliers typically have a standard minimum order of 50lb,” says sales director Jeff Neupauer. “The Color Store eliminates the need to carry unnecessary inventory.” The twelve concentrates are produced
with FDA-compliant ingredients. Colours include Salsa Red, Citrus Orange, Sunflower Yellow, Candy Pink, Jungle Green, Forest Green, Celestial Blue, Denim Blue, Earth Brown, Wolf Grey, Raven Black, and Winter White.
Laser sensitive pigments are also now available as
Alperform LS masterbatches and Alcolor Function LS combibatches including colorants beside the laser pigments. When inscribing with a laser, either the plastic expands or the plastic starts to carbonise. Expansion of the plastic leads to light markings, whereas carbonisation leads to dark markings. Both technologies now supplement the Albis masterbatch portfolio for applications where permanent marks are required, also offering higher flexibility and cost efficiency to converters. The Color Division of Teknor Apex has also an-
nounced developments aimed at processors of engi- neering thermoplastics. New colour concentrates that incorporate special additives for withstanding surface marring enable moulders of polycarbonate to manufac- ture products with built-in mar resistance, it says. While PC provides excellent strength, it can exhibit
unsightly surface blemishes caused by abrasion or rough handling, the company notes. New MarTek concentrates are said to increase mar resistance while imparting colour comparable in quality to that available with standard Teknor Color concentrates. All of the company’s standard colours are also available in MarTek formulations. In optical surface profilometry tests carried out by an independent laboratory, parts moulded with both standard and MarTek concentrates were examined for depth of abrasion caused by weights applied at varying forces. At forces of 3, 5, and 10 N, marring was virtually eliminated in parts moulded with MarTek concentrates. At 15 and 20 N, abrasion depth was reduced by up to 70%. “Increased mar resistance is particularly valuable in
parts for end-use products subject to extensive handling, such as CD/DVD discs, lenses, consumer electronics, medical diagnostic instruments, and hand-held devices like barcode readers,” says Edwin
