Heat Shrinkage Tester เครื่องทดสอบเพื่อหาเปอร์เซ็นต์การหดตัวของพลาสติกฟิล์ม

The  BRAVO HST Series Film Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heatshrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination.

Standards
ASTM D2732 - Standard Test Method for Unrestrained Linear Thermal Shrinkage of Plastic Film and Sheeting
ISO 14616 - Plastics -- Heatshrinkable films of polyethylene, ethylene copolymers and their mixtures -- Determination of shrinkage stress and contraction stress
DIN 53369 - Testing of plastic films -- determination of the shrinking stress

Specifications
-Temperature Range : Room temperature to  250?
-Temperature precision : ±0.2?
-Sample size : 140x140 mm
-Time range : 0.01s~99.99h
-Liquid medium  : Glycerin
