This formulation can be added to the resin or developed as a coating. Chemical grafting can increase the chemical resistance of polycarbonate against the following agents: solvents, acids, alkalis, salts, alcohols, hydrocarbons, nitriles and more
If you manufacture a product which contains polycarbonate and are looking to increase the chemical resistance of your product in order to give you a competitive edge then contact Advanced Polymer Solutions regarding our patented chemical process we will develop a customized formulation based upon your chemical resistance specifications.
Once we develop and thoroughly test the formulation it will become your property which can be patented under your name. APS can manufacture the final formulation in the desired quantities and supply the manufacturer with a pre-mixed, ready to use coating, additive or adhesive. Chemical resistance on polycarbonate formulation can be added to the resin or developed as a coating.
Polycaronate chemical resistant coatings are applied on the surface of substrates to improve the functional properties and durability. Conventional coatings need extensive surface preparation for adhesion and need to build up thickness for performance. This is not the case with APS’ coating formulations. Most APS coatings can be applied in one step with no or minimal surface preparation. In addition, due to the chemistry of APS’ chemical grafting process, thinner coatings can be used to achieve a higher degree of property performance. Delamination will not occur due to the chemical bond formed between the coating and the substrate with some subsurface penetration occurring through the use of molecular small and lightweight monomer.
Polycarbonate chemical resistant additives are added into the resin prior to extruding or molding in order to penetrate to matrix of the material.
Typical coating methods can be used such as dip, spray, roll, flow coat, etc. APS coatings can be formulated to be air dried, however, in the interest of time, heat or some energy source (i.e., UV or infrared lights) can be used.
APS can develop additives to incorporate into the raw material/resin prior to extruding or molding. In this case, the new properties will penetrate the matrix of the material. APS chemists will adjust the formulation to conform to the processing parameters used by the manufacturer. Due to the molecular bond formed by APS’ process, the new properties will not migrate and leach from the material over time, even under severe condition.
APS chemists have extensive experience in bonding the same or different substrates together. Materials that are difficult to adhere to are effectively bonded with APS’ process.Substrate failure will occur before adhesion failure. In addition, if two substrates with different coefficients of thermal expansion are bonded, an APS developed adhesive bonding action will not be affected. Such is not the case with conventional adhesives which cannot withstand the varying expansion and contraction of different substrates.
The UL Thermoplastics Testing Center (TTC) carries out tests for all major plastics applications, ranging from polyethylene to high-performance thermoplastics. The TTC works with companies involved in compounding, extrusion and injection molding, as well as raw materials producers and automotive manufacturers and their suppliers. The Center uses robots and state-of-the-art machinery to offer one-stop service for customers and can manage approximately 200 different tests for thermoplastics, as well as the production of granules and test pieces. The production of test pieces is carried out using fully automated injectionmolding machines. The center uses approximately 100 different injection molds for use in tests under UL, ISO and CAMPUS standards and also has complete production lines which enable the compounding of ABS and its blends, polycarbonates and industrial thermoplastics in quantities ranging from 1.3 to 100 kilograms.
