Unrestrained Thermal Shrinkage Rate Tester Shrinkage Tester Oil Bath Method ASTM D2732

The Shrinkage Tester is a critical instrument designed to measure the unrestrained linear thermal shrinkage of plastic films and sheets under specific temperature conditions. This device operates based on the oil bath method, a highly effective and precise technique to determine the shrinkage rate of materials when subjected to heat. This Shrinkage Tester complies with industry standards such as ASTM D2732 and GB T13519, ensuring reliable, accurate results for laboratory use.

Key Features of the Shrinkage Tester

• P.I.D. Temperature Control: The Shrinkage Tester features advanced P.I.D. (Proportional, Integral, Derivative) temperature control, ensuring precise temperature regulation throughout the testing process. This helps maintain accurate and consistent results for each test cycle.

• High Precision Timer: Equipped with a high-precision timer, the Shrinkage Tester ensures accurate measurement of the time required for shrinkage, crucial for producing repeatable and reliable results.

• Alarming Function: The instrument is designed with an alarming function to notify users of any deviations or when a test cycle is complete, providing added convenience and safeguarding the integrity of the testing process.

• Stable Heating of Fluid Medium: One of the standout features of this Shrinkage Tester is its ability to maintain stable heating of the fluid medium (oil bath), ensuring the specimen experiences consistent thermal conditions throughout the test, which is essential for accurate shrinkage measurement.

• Standard Square Metal Clamp & Free Shrink Holder: The Shrinkage Tester includes a standard square metal clamp and an optional free shrink holder, allowing flexible specimen mounting and preventing unnecessary distortion during testing.

Technical Specifications of the Shrinkage Tester

Compliance and Standards

The Shrinkage Tester is designed to comply with established international standards, including:
