Abrasion Resistance

PolyCarbonate

Our Clients  come to APS for our scientific expertise when the endeavor is enhancing an existing product, improving manufacturing  efficiencies, or discovering a solution that  creates an innovative new product.   

 

Our specialists  have a deep understanding  of both raw materials and production processes.  Their focus is effective and efficient solutions  to help you reduce costs and generate added  value. 

  

Abrasion resistance on polycarbonate formulation can be added to the resin or developed as a coating. Please note: while the chemical grafting process is the same for all plastics the grafting initiator, monomers, and catalyst are vastly different depending on the type of plastic and desired properties. Each project is custom tailored to meet our client's specifications.

The Mechanism of Grafting

Abrasion Resistance Polycarbonate

​

APS  substrate activators have the unique capacity of removing active hydrogens from substrates and initiating the

growth of polymer chains at the site. By removing these hydrogens anelectron is removed forming a free radical. This free
radical site needs an electron to stabilize its site andwill share the electron with the present monomers
forming the chemical bond. The following representsthe four step chemical grafting process:

​

1)        Activation: free radical formation
substrate activator
MOH_________  MC*


2)        Chemical Bonding of monomers:
MO
(CH2 — CH)n
x        x = functional group that changes with
each monomer and determines the property


3)        Formation of small polymer side chains: n =
controlled
chain length of monomers (same or varied)


4)        The reaction is then terminated with a specific
formulation ingredient so that all reactive components
are exhausted.

Our monomers can be added to the resin or
developed as a coating.

Abstract 

  

This specification covers the quality requirements for cut sizes of architectural flat glass-clad polycarbonate (GCP) for use in buildings as security, detention, hurricane/cyclic wind-resistant, and blast and ballistic-resistant glazing applications.  Architectural polycarbonates furnished under this specification shall be of the following: GCP, single-core (SC),  multiple cores (MC), and  others (O).

 

The polycarbonates shall be examined by means of the following:  security test, impact test for safety glazing, missile impact and cyclic pressure test, security glazing test, air blast loading test, detention glazing test, bullet resisting glazing test, burglary resisting test, visual inspection, and transmittance test.

 

The materials shall also adhere to specified size and dimensional requirements and maximum allowable blemishes in form of bubbles, edge boil blow-ins, fuses, single strand lint hairs, inside dirt spots, areas of concentrated lint, delamination and discoloration, short inter-layer and unlaminated area chips, streaks and scuffs, white scratches, carbon specks, and drizzles. 

  

Scope 

1.1 This specification covers the quality requirements for cut sizes of glass-clad polycarbonate (GCP) for use in buildings  

as security, detention, hurricane/cyclic wind-resistant, and blast and ballistic-resistant glazing applications. 

  

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for 

information only. 

  

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the  responsibility of the user of this standard to establish appropriate safety and health practices and determine the  applicability of regulatory limitations prior to use. 

   

ASTM Falling Sand Test 500 lbs. (Abrasion Resistance Polycarbonate) of sand is poured on the treated surface, Results:  

no noticeable chipping, peeling, or wearing away of chemically bonded coating at <1 mil thick. 

  

ASTM Taber Abrasion Test Federal Test Method Std. No. 141 using a CS 17 wheel, (Abrasion Resistance  

Polycarbonate) a 1000 gram load at 70 rpm for 10,000 cycles. Results: no loss of coating at 51 mils thick. 

​

We have successfully grafted such properties as abrasion resistance, chemical resistance, flame resistance, UV resistance,  

oxygen and moisture barrier, increased structural strength, adhesion to other materials, and flavor barrier onto numerous  

plastics such as:
