Product Description Product OverviewHCPE is a type of Chlorinated Polymer which contains chlorine at 65-69%. It is transparent, hard and brittle thermoplastic resins. It has high chemical stability, good salt water resistance and good ultraviolet resistance. It is readily soluble in organic solvents such as toluene, xylene and esters, forming a colorless to pale yellow, transparent solution. When this solution is applied to the surface of metal, concrete, paper etc., the solvent readily vaporizes at room temperature to leave a transparent, hard and lustrous glass-like film. This film resists the permeation of moisture and oxygen gas, and shows high resistance to various chemicals such as acids and alkalis. It protects the substrates from corrosion, and also serves as a top coating for decorative purposes.

High-Performance Structural AdhesivesApplications:·Automotive Manufacturing: Bonding metal-to-plastic components (e.g., door panels, dashboard brackets), requiring oil resistance, vibration resistance, and high-temperature tolerance (-40°C to 120°C).·Aerospace: Lightweight composite bonding (carbon fiber/aluminum alloys), where HCPE provides strength and fuel corrosion resistance.2. Sealants & Gap FillersApplications:·Construction Sealants: Weatherproofing curtain wall joints, window/door gaps (UV and rain resistance).·Industrial Equipment Sealing: Chemical pipelines, storage tanks (HCPE with ≥40% chlorine for acid/alkali resistance).3. Pressure-Sensitive Adhesives (PSA)Applications:·Electronic Tapes: High-temperature labels, smartphone screen mounting tapes (stable at >80°C).·Industrial Tapes: Oil-resistant surface protection films, pipe-wrapping tapes.4. Hot-Melt AdhesivesApplications:·Packaging: Carton sealing, bookbinding (fast curing for high-speed production lines).·Footwear: Midsole-to-upper bonding in sports shoes (flexible and non-toxic).5. Conductive/Shielding AdhesivesApplications:·Electronics: EMI shielding adhesives for 5G devices, circuit board grounding (with conductive fillers like silver powder).·EV Batteries: Bonding battery modules to prevent electromagnetic interference (EMI).AdvantageKey Performance Advantages of HCPE in AdhesivesPropertyBenefits for AdhesivesTypical RequirementsHigh Chlorine Content (≥40%)Enhanced chemical resistance (oil, acids)Chlorine: 40%-45%, volatiles ≤0.3%Low MFR (0.1-2.0)High viscosity for solvent-free formulationsMFR 0.5-1.5 g/10min (190°C)High Elongation (≥500%)Superior flexibility and peel resistanceTensile strength ≥15 MPa, elongation ≥500%Flame Retardancy (UL 94 V-0)Meets fire safety standards in electronics, EVsOxygen index ≥28%1. High-Performance Structural AdhesivesAdvantages:Chemical Resistance: Withstands gasoline, lubricants, and hydraulic fluids.Flexibility: Accommodates thermal expansion and mechanical stress, reducing crack risks.2. Sealants & Gap FillersAdvantages:Long-Term Durability: Outdoor service life exceeding 10 years, outperforming silicone-based sealants.Strong Adhesion: Bonds to PVC, metals, concrete, and other substrates.3. Pressure-Sensitive Adhesives (PSA)Advantages:Tunable Tack: Adjust chlorine content (30%-45%) to balance initial adhesion and holding power.Weather Resistance: Maintains adhesion stability in humid or fluctuating environments.4. Hot-Melt AdhesivesAdvantages:Low-Temperature Processing: Tunable melting point (120°C-160°C) reduces energy consumption.Eco-Friendliness: Solvent-free, compliant with VOC regulations (e.g., EU REACH).5. Conductive/Shielding AdhesivesAdvantages:Electrolyte Resistance: HCPE matrix resists corrosion in battery environments.Nanocompatibility: Compatible with carbon nanotubes, graphene, and other nanomaterials.
