Special additive masterbatch increases visibility in green house

new masterbatch called Spectrafoil based on optical brightener that increases the light transmission in the visible range of radiation has been developed by a German masterbatch company. The masterbatch also absorbs incoming UV–A light, and provides a long life and no chemical degradation.

Scratch resistant coating on cross linked polystyrene

A transparent thin coating or film to be applied on cross linked polystyrene blocks that will be in contact with an aqueous couple gel to improve scratch resistance and surface hardness with the following parameters.
The coating must be optically transparent or opaque but not coloured, from a acoustic point of view it must be has acoustic impedance confront able with water
May not change the sound properties of the polymer
The thickness of the coating must be in the order of 1 micron
The minimum acceptable hardness value is 55 / 60 HV (HV meaning Hardness in Vickers. It must be emphasized that we made a microhardness test.)
Shelf life must have a minimum of 2 years

Non-Contact IR Analysis simplifies on line quality control

A new method of mid-infrared analysis allows on-line monitoring of both the composition as well as physical properties of a plastic while it is being compounded or extruded. Up to now, mid IR spectroscopy was limited to use in the laboratory and only for gases. The new technique, Transient Infrared Spectroscopy (TIRS), developed at the Ames Laboratory, a U.S. Dept. of Energy Lab, performs non-contact, real-time monitoring of solid or melt-phase process streams. This new system (TIRS) is simple to assemble from off the shelf components, using either a Fourier Transform Infrared (FTIR) spectrometer or a non-dispersive IR detector.

Challenging time ahead for biopolymers to prove commercial viability

Europe is the largest market for biopolymers, with 60% of total production centered there. Average global growth is 12.6% pa, and the overall market is expected to grow from 65000 MT in 2005 to 100000 MT in 2010. Most of that usage will still be in two applications: compost bags and loose-fill packaging.

CPVC offers benefits for chemical processing industry

Since its introduction into the market in 1958, CPVC found its main use in the manufacture of pipe, valves and fittings and associated industrial parts, where higher temperature and chemical resistance are of crucial importance. CPVC offers special benefits in a highly corrosive and high temperature environment, and when combined with cost advantages, CPVC became very appealing alternatives to metals.
