| ACCEPTED PRODUCTS AND SYSTEMS FOR ROOFSTAR FIVE (5) YEAR, ROOFSTAR TEN (10) YEAR, AND ROOFSTAR FIVE (5) YEAR WATERPROOFING GUARANTEES.
The table or tables shown below provide basic material data and links to more information about the materials, including manufacturers' published Technical Data sheets, but this information not intended for use as a comparison of material performance or quality. It is the sole responsiblity of the design authority to assess the performance capability and material suitability for specific design requirements. The materials listed are those which have been accepted by the RCABC Guarantee Corp. (RGC) upon application by the manufacturer/supplier, in compliance with RGC Policy A-041, and are materials for which RoofStar Guarantee Certificates are available. The acceptance of these materials in no way reflects on the quality or performance of other materials not listed. The materials and guideline specifications are listed under the name of the manufacturer and/or supplier of the primary membrane material; except that RGC has issued the guidelines on traditional built-up roofing systems (BUR) incorporating organic and glass felt primary membranes. |
- Atactic polypropylene (APP) polymer modifiers are by-products of the polymerization of propylene gas into isotactic polypropylene (used for injection molding and extrusion). APP has a lower melting point and is more compatible with asphalt than isotactic polypropylene.
- Bitumens modified with APP can display improved physical and mechanical properties. The improved properties are only possible if the APP is finely dispersed throughout the bitumen to avoid separation during manufacture and service.
- APP modification of bitumens can impart the following changes in properties:
- increased softening point
- improved ultraviolet radiation resistance
- improved low temperature flexibility
