Lab Biaxial Film Stretcher For Polymer Materials

   

       Lab Biaxial Film Stretcher for Polymer Materials is a state-of-the-art laboratory instrument designed for the precise stretching and characterization of polymer films. This advanced equipment is widely used in research and development to study the mechanical, thermal, and optical properties of polymer materials under controlled biaxial stretching conditions. With our laboratory stretching machine for monoaxial and biaxial film orientation, it is possible to test films and sheets in a very simple and economical manner - in the sequential as well as in the simultaneous stretching mode.

Features Of Lab Biaxial film Stretcher for polymer materials

1.High strength European standard integrated frame, Attractive and durable.

2.Touch-screen integrated commercial computer control, humanized structure design, more convenient operation.

3.Two-way high performance servo motor driven to achieve one-way or two-way variable speed stretching.

4.One-way limited, one-way unrestricted, bidirectional synchronization, bidirectional asynchronous stretching methods can be performed.

5.Multiple PID temperature control points, make the temperature control accuracy higher, more comprehensive and more real.

6.Newly designed user interface – intuitive & easy machine control

How to use the Lab Biaxial Film Stretcher For Polymer Materials

Sample Preparation

• Cut the polymer film into a square or rectangular sample of the required dimensions (typically specified by the equipment manual).
• Ensure the sample is free from defects, wrinkles, or contamination.

Mounting the Sample

• Secure the polymer film sample in the clamps or grips of the biaxial stretcher.
• Ensure the sample is evenly tensioned and aligned in both directions (machine and transverse).

Setting Parameters

• Set the desired stretching ratio/speed/temperature for both directions.

Stretching Process

• Initiate the stretching process according to the set parameters.
• Use cameras to monitor the sample's behavior during stretching (e.g., stress-strain response, thickness variation).

Post-Stretching

• If required, hold the sample at the stretched dimensions for a specified time to allow stress relaxation or crystallization.
• If the sample was heated, cool it down to room temperature while maintaining the stretched state.
• Carefully release the sample from the clamps to avoid damaging it.
