Beijing Organic Chemical Factory EVA Y2022 (14-2)

The technical data sheet (TDS) of EVA Y2022 (14-2) material from Beijing Organic Chemical Factory corporation; if there are discrepancies, please refer to the official website of Beijing Organic Chemical Factory.

Features & Benefits

• Outstanding Optical Performance: Features a film haze of only 1.9% and a gloss of 82%, offering good transparency suitable for film products requiring high visibility.

• High Ductility and Flexibility: Transverse elongation at break reaches up to 720%, allowing the material to withstand substantial stretching deformation with strong bending resistance and low brittleness.

• Balanced Tear Performance: Stable transverse and tear strength in both directions, providing good resistance to tearing damage during processing and application.

• Reliable Electrical Insulation Characteristics: Dielectric strength of 670 kV/cm and a stable dielectric constant, making it suitable for low-voltage insulating film applications.

• Stable Thermal Processing Window: Melting point of 95°C and Vicat softening point of 70°C, providing a controllable processing temperature range compatible with film production processes such as extrusion lamination.

Applications

• Packaging Film Industry: Inner base materials for flexible food packaging and composite packaging; relies on high transparency and high elongation to suit packaging heat-sealing and folding scenarios.

• Photovoltaic Auxiliary Materials: Can be used as a substrate film for photovoltaic module encapsulation; relies on good light transmission and flexibility to suit lamination processes.

• Electrical Insulation Films: Insulating protective films for low-voltage electronic components; utilizes stable dielectric properties to provide isolation and protection.

• Composite Protective Films: Surface protective films for metal sheets and plastic sheets; balances transparency and tensile properties for easy lamination and peeling.

• Daily Elastic Films: Elastic stretch films and sealing films suitable for products requiring repeated deformation and flexible wrapping.

Frequently Asked Questions (FAQs)

Q1: Is drying treatment necessary before processing EVA Y2022 (14-2)?

A1: As a film-grade EVA product, it exhibits low moisture absorption under normal storage conditions. If storage humidity is relatively high, moisture content testing is recommended in advance. If moisture content exceeds the limit, low-temperature drying can be performed to prevent bubbles and surface defects during processing.

Q2: What are the main selection differences between 14% VA EVA and low VA content EVA?

A2: Higher vinyl acetate content results in better EVA flexibility, transparency, and adhesion, though rigidity decreases. With a 14% VA content, Y2022 (14-2) is softer and offers better light transmission than low-VA grades. Low-VA EVA provides higher rigidity and better temperature resistance, making it suitable for scenarios requiring greater structural strength.

Q3: Is export supported for this EVA film, and can compliance documents be provided?

A3: Foreign trade export is supported. TDS, MSDS, and batch-specific COA quality inspection reports can be provided. The material meets basic environmental compliance requirements such as RoHS and REACH, and can be used for overseas customer factory audits and product declarations.

Q4: Is this film suitable for use under long-term high-temperature conditions?

A4: With a Vicat softening point of 70°C, this material is not suitable for long-term continuous high-temperature environments exceeding 70°C, as softening and deformation will occur. The continuous operating temperature of the end product must be verified during material selection.
