Product DescriptionSpecificationCore Specifications:Mylar, also known as BoPET (Biaxially-oriented polyethylene terephthalate), is a polyester film made from stretched polyethylene terephthalate (PET)Thickness Range: 19–50 μm (0.75–2.0 mil)Common: 23 μm, 28 μm, or 35 μm (balance of cost and performance).Tolerance: ±5% (tighter tolerances preferred for automated lines).Width & Length:Width: Matched to FRP sheet width (e.g., 1m–3m), slit tolerance ±1mm.Length: 500m–10,000m rolls (minimizes splicing during production).Surface Properties:Release Side: Low-adhesion surface (silicone-coated or plasma-treated) for easy demolding.Back Side: Often untreated or lightly treated to prevent roll blocking.Surface Energy: 38–45 dynes/cm (release side), >50 dynes/cm (back side if adhesion needed).Roughness (Ra): 0.1–0.5 μm (smooth finish for high-gloss FRP surfaces).Thermal Stability:Max Temp: 220°C (short-term), 150–180°C (continuous).Shrinkage: <1.5% at 150°C (30 min) to prevent wrinkles during curing.Mechanical Properties:Tensile Strength: ≥150 MPa (MD), ≥250 MPa (TD).Elongation: 100–180% (MD), 70–120% (TD).Stiffness: 4,000–6,000 MPa (prevents sagging on molds).BOPET film′s Importance in FRP Shee Lamination ProcessBOPET film plays a mission-critical role in FRP sheet lamination, acting as the carrier for polyester resin and fiberglass composite material. Its importance extends far beyond a simple release layer – it directly impacts product quality, production efficiency, and cost control. Also using BOPET film with corona treatment or using heat sealing type film , it will stick to the FRP sheet and serve as a protective layer. Packing & DeliveryWe offer tow kinds of packing for you to choose.The first one is wooden case packaging which protect the product well. The second is with pallets, its more economic. Company ProfileWe are a professional FRP sheet producing factory with 3 continuous lamination production lines and we are consuming a large quantity of raw materials like fiberglass direct roving, BOPET film and resin.So we can recommed you the better raw material for your FRP sheet production.
