M710B Chopped Strand Mat for hand lay-up (Spanish)
Market Vision 23 (March 2016) – Enlarged, flexible choice of emulsion bonded CSM for hand lay-up and closed mold applicationsOwens Corning has broadened its range of emulsion bonded chopped strand mat (CSM) products with the addition of M6X1 for large and thick parts. Together with M705 CSM, they deliver key performance properties for a wide range of different processes and application requirements.
M6 X1M6 X1 is a medium fiber, multi-chop length chopped strand mat bonded together using an emulsion binder. The emulsion binder provides superior handling properties compared to powder bonded mats. The chemistry and chop length used in M6 X1 allows it to conform well in contoured molds.
M133The M133 chopped strand mat is made with medium size strands of Advantex® Glass, chopped at different lengths to improve the tensile strength and held together by a powder binder which is extremely soluble in styrene. The basic strand has a sizing system containing a silane coupling agent. This sizing system combined with the binder properties make M133 suitable with PU resins. Advantex® glass is a patented glass formulation meeting ASTM D 578 as a boron-free corrosion resistant E-CR glass fiber and ISO 2078 recommendation for use in acid environments.
M103This product is produced using Advantex® glass fiber. Advantex® glass fiber combines the electrical and mechanical properties of traditional E-glass with the acid corrosion resistance of E-CR glass. The M103 chopped strand mat is made with very low size strands of Advantex® Glass Roving, held together by a powder binder which is extremely soluble in styrene
E-CSME-CSM is made from E-glass low size chopped strands held together by an emulsion binder which makes it perfectly suitable for use with polyester resins. The basic strand has a sizing system containing a silane coupling agent.
M720

M720 is a medium-fine fiber, rapid wetting chopped strand mat that is composed of multi compatible saline sized chopped glass fibers, bonded together with a small amount of highly soluble polyester powder binder. M720 can be used for: Matched Metal Die wet molding; Open mold applications requiring highly conformable mat.

M821B

M821B is designed to be compatible with polyester, epoxy, polyurethane and vinylester resins and used in process like RTM, Vacuum, S-RIM and Press Molding where is necessary good fiber washing resistance, softness and good conformability.

M710B

M710B is designed to be compatible with polyester, epoxy and vinylester resins and used both as gel coat backup and standard laminate reinforcement for most contact molding applications where quick wetting, rapid air release, good conformability and low resin consumption are desired.

M723AM723A is a medium-fine fiber, rapid wetting chopped strand mat and is composed of silane sized multi-length (one to two inch) chopped glass filament bundles that average 16,500 yards/pound (30 tex or g/km). It is bonded together with a small amount of highly soluble powdered polyester binder and is designed to be randomly oriented and multi-resin compatible.
M113

The M113 chopped strand mat is made with low size strands of Advantex® Glass Roving, held together by a powder binder which is extremely soluble in styrene.

The basic strand has a sizing system containing a silane coupling agent. This multi-purpose mat is used in numerous applications; this explains the extensive range of weights and widths available.

M705

M705 mat is made of randomly oriented chopped glass strands bonded together in mat form using an emulsion binder. The emulsion binder uniquely bonds the mat so that it conforms rapidly to highly contoured molds. It is a porous, well bonded mat which maintains its integrity during the impregnation process and provides an uniform wet-through rate. The emulsion binder produces superior handling properties compared to powder bonded mats.

M123

The M123 chopped strand mat is made with medium size strands of Advantex® Glass Roving, held together by a powder binder which is extremely soluble in styrene. The basic strand has a sizing system containing a silane coupling agent. This sizing system combined the binder properties make M123 suitable with epoxy, vinylester and anti-corrosion resins.
