Advanced Polymer Solutions  has fine-tuned
a unique process of
chemical grafting which
allows manufacturers to permanently add or
improve the performance of polystyrene 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.
Polystyrene grafting can be
added to the resin or used as a coating
improving it's properties. If your product is
polystyrene, chemical grafting can improve the
physical, mechanical, thermal, electrical,
chemical and gas permeation of

educated and experienced in polymer and organic chemistry, research and
development and engineering. As a result, APS offers over 75 years of
combined expertise in offering custom solutions to manufacturers in the
areas of product improvement and high impact commercialization
solutions to reduce costs and eliminate hazardous materials.

Frequently Asked Questions

Can Chemical Grafting impart desirable properties of an
expensive plastic onto a less expensive plastic?
Yes, the less expensive would then have the properties of a
more expensive plastic resulting in tremendous cost

Can Chemical Grafting work on any substrate?
No, although we have a vast array of activation monomers,
they cannot activate every substrate. Email us @ for a complete list of
substrates which cannot be grafted.

Can my company patent the formulation once it is
Yes, you will own the formulation, we will assist in
obtaining your patent.

Are the formulations safe?
Yes, The ingredients in all APS formulations will be
completely safe, can be water based in many cases, and
will conform to OSHA, EPA and, if required, FDA guidelines.

Can a chemically grafted formulation be used to attach
two different types of plastic?
Yes, in this case two different types of monomers will be
used to activate the substrate. This application would be
used as a coating between the two substrates.

Can the formulation be added to ink?
Yes to improve adhesion to various substrates, glass,
textiles, etc. Also to impart desirable properties into the ink
such as scratch resistance.

Once developed can Advanced Polymer Solutions
manufacture the coating or additive?
Yes, we can manufacture the formulation in any amount to
meet your requirements.

When grafting onto metals is any heat source required?
No, our activation monomers will bond to the metal forming
a covalent bond.
