BMW TL 7 120 777.6 PVC Film Features for Sun Visors

The standard "BMW TL 7 120 777.6 Specification for PVC film for sun visors," developed by BMW, a multinational vehicle manufacturer headquartered in Germany, specifies the delivery conditions and quality guidelines for PVC compact film for sun visors. The required specifications apply to planar starting materials as delivered and to partially finished parts (unless otherwise specified). The purpose of this standard is to ensure the consistent quality of the PVC compact film to be processed.

Samples and initial shipments must meet the requirements specified in this standard and must be accompanied by a test report only. All changes to the formula, production procedure, or technical nature must be reported to the specialized department issuing the release and require a new written release.

The type designation is related to the release status; any change requires additional designation. For a complete evaluation and release to be issued, the processing, component, and functional testing described in the relevant quality/technical specifications must be performed. For example, properties such as contamination/cleaning properties and surface wear resistance fall into this category.

The supplier must ensure that the required characteristics and values ​​are maintained by continuous testing of the product before delivery.

The plain stock material must match the released master sample in color, grain, luster and feel.

PVC films used in automotive sunshades are designed to meet specific performance and safety standards. These films offer durability, UV resistance, and aesthetic appeal, ensuring longevity and comfort in vehicle interiors.

The main characteristics of PVC films for sunshades include:

• Thickness: Typically ranges from 0,2 mm to 2,0 mm and provides flexibility and structural integrity depending on design requirements.
• UV resistance: Fortified with UV stabilizers to prevent degradation and discoloration over time, maintaining clarity and appearance.
• Light transmission: High transparency is essential, with some films providing over 87 percent light transmission while blocking approximately 90 percent of harmful UV radiation.
• Heat shielding: Some films are designed to reduce heat buildup inside the vehicle by absorbing some infrared light. For example, some films absorb up to 28 percent of infrared light, improving passenger comfort.
• Mechanical properties: Exhibits high tensile strength (minimum 45 MPa) and elongation at break (minimum 60 percent) and provides resistance to stretching and tearing.
• Compliance standards: Manufactured to meet automotive safety standards such as ISO 3795, which concerns the flammability of materials used in vehicle interiors.
• Surface finish: Usually double polished to achieve optimum clarity and a smooth surface, contributing to the aesthetic quality of the sun visor.
• Process compatibility: Suitable for a variety of manufacturing processes, including high-frequency welding, hot air welding, and sewing, facilitating integration into different sun visor designs.

These features ensure that the PVC films used in sun visors provide the necessary durability, safety and comfort expected in automotive applications.

The BMW TL 7 120 777.6 standard is part of BMW's internal technical delivery conditions. These are proprietary specifications used to ensure that all materials and components supplied to BMW meet stringent quality, performance, and safety standards. This standard is deemed necessary in this context for the following reasons:

• Consistent quality across global suppliers: BMW operates a global supply chain. This standard ensures that every supplier of PVC film for sunshades produces to the same specifications, regardless of location.
• Safety and regulatory compliance: Automotive interiors must comply with flammability, toxicity, and emissions regulations. This standard defines:
  • Fire resistance
  • Emissions of volatile organic compounds (VOCs)
  • UV resistance to prevent deterioration

These help ensure passenger safety and regulatory compliance in every market where BMW sells vehicles.

• Material performance requirements: these and similar standards define:
  • Thickness, strength and flexibility of the film
  • Color fastness and abrasion resistance
  • Temperature tolerance

This is particularly important for sun visors, which must perform well in both hot and cold conditions and maintain a premium look and feel over time.

• Visual and tactile consistency: Look and feel are important in premium vehicles. This standard ensures:
  • Uniform surface texture and gloss
  • Consistent coloring and finish
  • Seamless integration with other interior components
• Manufacturing compatibility: this standard may include tolerances for:
  • High frequency welding
  • Stitch or stitch
  • Adhesion to substrates (such as molded foam)
• This ensures that the material integrates seamlessly into BMW's production lines.
