Product Materials and Manufacturing Process Flow

The manufacturing of high-quality window seal strip adhesive products involves a meticulous process, beginning with material selection and culminating in rigorous quality control. Leading window seal strip adhesive factories leverage advanced polymer science and precision engineering.

Key Materials:

• EPDM Rubber: Excellent resistance to weathering, ozone, UV radiation, and extreme temperatures (-40°C to +120°C). Widely used for its durability and flexibility.
• Silicone Rubber: Superior high-temperature resistance (+200°C), excellent flexibility, and chemical inertness. Ideal for specific applications requiring medical-grade or food-grade compliance.
• PVC (Polyvinyl Chloride): Cost-effective, good resistance to abrasion, and available in various hardnesses. Often used for less demanding applications or as co-extruded components.
• TPE (Thermoplastic Elastomers): Combines the properties of rubber and plastic, offering good flexibility and recyclability.
• Adhesives: Pressure-sensitive adhesives (PSA) like acrylic, rubber-based, or silicone-based, providing strong, long-lasting bonds to various substrates.

Manufacturing Process Flow (Example: Extruded Rubber Gaskets):

The production of products like aluminium window rubber glazing gaskets typically follows these stages:

1. Material Compounding: Raw polymer (e.g., EPDM granules) is blended with additives such as curing agents, fillers (carbon black, silica), plasticizers, processing aids, and colorants in a high-shear mixer. This step is critical for achieving the desired physical properties (hardness, tensile strength, elasticity).
   

   Figure 2: Precision material compounding for optimal performance.

2. Extrusion: The compounded material is fed into an extruder, where it is heated and forced through a die to create the desired profile (e.g., a specific gasket shape). This continuous process is highly precise, ensuring uniform dimensions and surface finish. Some `window seal strip adhesive companies` utilize co-extrusion for multi-material profiles.
3. Curing (Vulcanization): The extruded profile is then subjected to heat in a continuous curing oven or via a salt bath. This process, known as vulcanization, cross-links the polymer chains, transforming the material from a plastic-like state into a highly elastic and durable rubber. Curing parameters (temperature, time) are critical and strictly controlled.
4. Adhesive Application (if applicable): For self-adhesive strips, a layer of pressure-sensitive adhesive (PSA) is applied to one side of the cured profile, often with a release liner. This ensures easy and secure installation.
5. Cutting and Finishing: The continuous strip is cut to specified lengths. Additional processes may include punching holes, corner molding, or applying surface treatments.
6. Quality Control and Testing: Each batch undergoes rigorous testing to ensure compliance with standards such as ISO 3302 (dimensional tolerances), ASTM D2000 (rubber properties), and specific industry standards (e.g., DIN, SAE). Tests include hardness (Shore A), tensile strength, elongation at break, compression set, ozone resistance, UV resistance, and accelerated aging. A leading window seal strip adhesive manufacturer will ensure these tests are routinely performed.

The service life of these products can extend from 10 to 30 years, depending on the material, application, and environmental conditions. Our products, such as the aluminium window rubber glazing gaskets, are engineered for long-term performance, offering exceptional energy saving and corrosion resistance in typical application scenarios.

Technical Specifications and Performance Parameters

Selecting the appropriate window seal strip adhesive requires a thorough understanding of its technical specifications. These parameters dictate the product's suitability for specific applications and its long-term performance.

Key Parameters for Rubber Glazing Gaskets:

• Hardness (Shore A): Typically ranges from 50 to 80 Shore A, influencing compression and sealing effectiveness.
• Tensile Strength (MPa): Indicates the material's resistance to breaking under tension (e.g., 5-15 MPa for EPDM).
• Elongation at Break (%): Measures the material's ability to stretch before breaking (e.g., 200-500% for EPDM).
• Compression Set (%): Quantifies the permanent deformation of the material after prolonged compression, critical for maintaining sealing force over time. Lower values are better (e.g.,
• Temperature Range: Operating temperatures, crucial for hot or cold climates. EPDM generally performs well from -40°C to +120°C.
• Ozone Resistance: Essential for outdoor applications to prevent cracking and degradation. EPDM offers excellent resistance.
• UV Resistance: Protection against solar radiation, preventing material breakdown and discoloration.
• Water Absorption (%): Low water absorption is critical to prevent swelling and degradation of sealing properties.
