We always have a substantial supply of desired resin products in stock, ready for distribution. If you’d like to be added to our e-mail list and be alerted whenever we have a surplus, or, are looking to make a special purchase, contact Mike Rosenthal directly at (401) 767-2700 ext. 101 or via e-mail at miker@tpgoa.com The Plastics Group offers its customers free color compounding By having TPG do the color blending, molders also receive certain operational benefits. These include: First, no blending is necessary and TPG ensures the consistency of the color from lot to lot. Press operators can pay more attention to the other elements of the production process. Costs for blender acquisition and maintenance are reduced or eliminated. Concentrate no longer has to be stored or handled. Regulatory issues associated with some concentrate materials may also be simplified. The Plastics Group offers commercial (as opposed to critical) color-matching capabilities on a no-charge basis. Processors would normally supply TPG with a color chip or part for matching. TPG will work with our color concentrate suppliers to develop a color concentrate which will not impact the required physical properties of the finished product and ensure lot-to-lot consistency in color.
