495 conventional roving is manufactured with state-of-the-art equipment, innovative chemistry and a major commitment to statistical process control. The quality Management Program of Owens Corning manufacturing is certified as meeting the requirements of ISO 9002. Owens Corning 495 roving is manufactured from a collection of continuous glass filaments gathered, without mechanical twist, into a single bundle. The roving is then wound and shipped in a tubeless package ready for use in cstomer continuous operations.PRODUCT APPLICATION:
The “495” designation refers to a high performance sizing that has proven world wide acceptance in a multiple range of highly demanding applications such as pipes or tanks for wastewater treatment and chemical outlets. 495 roving is also suitable in panel laminating or can be used as choppable roving in reinforced complexes. The 495 sizing is compatible with polyester and vinyl ester resin systems. FEATURES:
• Corrosion resistance
• Low static and fuzz/excellent runnability
• High laminate properties
• High package and pallet weight BENEFITS
(1)Quality and Consistency:
Statistical process control is applied to the 495 roving manufacturing process to help ensure consistent quality lot-to-lot and doff-to-doff. Every aspect of the manufacturing process is under control and analyzed for never-ending improvement.
By using 495 roving, composites applications, such as GRP pipe, can last longer and have effective service life. Fabricators can avoid the extra cost of linings, coatings, cathodic protection, wraps or other forms of corrosion protection. Moreover, lower maintenance costs can be expected when using 495 versus standard products on the market. Finally, hydrolytic characteristics have essentially shown to be constant over time when using 495 roving.
(3)Low static and Fuzz - Excellent Runnability:
Owens Corning’s unique manufacturing process results in a roving with unparalleled runnability from package to mold. The strand chemistry for the 495 roving is specifically designed to virually eliminate static and reduce fuzz/fly (broken filaments at contact points). This minimizes interruptions and improves overall productivity, while enhancing operator comfort and safety.Microprocessor controlled yield, coupled with unrivaled packaging ensure smooth and consistent glass delivery.
(4)High laminate properties:
Owens Corning 495 roving is manufactured from a glass formulation yielding excellent mechanical properties in both standard and corrosive media. The 495 chemical treatment is based on silane coupling agents to ensure excellent bond between the glass fibers and a wide range of polyester and vinylester resins. Statistical process control in the application and curing of the 495 sizing helps to ensure consistently high mechanical properties in the finished laminates.495 laminates, based on general purpose, isophthalic and vinylester resins, exhibit mechanical properties equal to or better than other competitive rovings. The strong bonding between the glass fibers and the resin matrix, due to the 495 chemistry, is highly resistant to hydrolytic attack. This makes 495 a roving of choice for highly demanding applications in the construction and corrosion applications.
(5)High package and pallet weight:
The large package size (30 cm/12 in diameter) reduces material handling costs, while the Bulk-Pak packaging system minimizes packaging and waste disposal. More product per package allows longer run time before more material is needed at the roving station.
