Polyethylene Additives

Advanced Polymer Solutions has fine-tuned a unique process of chemical  grafting  which allows manufacturers  to permanently add or improve the performance of polycarbonate while retaining its existing characteristics.

 

This process involves substrate activation and the attachment and polymerization of monomers that contribute the desired properties onto the backbone of the substrate using safe, effective organic chemicals. Because a covalent bond is formed, the molecularly bonded formulation is permanent and cannot be leached, even under severe conditions. 

 

Polyethylene grafting  can be added to the resin or used as a coating improving its properties. If your product is polyethylene, chemical grafting can improve the physical, mechanical, thermal, electrical, chemical, and gas permeation of polyethylene.

Polyethylene Additives

Coatings are applied on the surface of substrates to improve 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's 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 molecularly small and lightweight monomers. 

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.

Laminates (Adhesives) 

 

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. Again, no or minimal surface chemical attachment of one substrate to the other.  Consequently, substrate failure will occur before adhesion failure. In addition, if two substrates with different coefficients of thermal expansion are bonded, and APS developed adhesive's bonding action will not be affected. This is not the case with conventional adhesives which cannot withstand the varying expansion and contraction of different substrates. 

Application of all APS chemical grafting formulations can apply at ambient temperatures and normal atmospheric conditions.
