Product catalog summary

Introduction
With the rise in living standards, consumer expectations for household products have increased, leading to higher industry standards. The focus on environmental protection and health has also intensified, especially due to recent global events.

Flexible Polyurethane Foam
This material is valued for its softness, high resilience, flexibility, light weight, and chemical stability. It is commonly used in furniture, car seats, sofas, and mattresses.

Testing Items for Flexible Polyurethane Foam

Appearance Quality: Inspects color, pores, cracks, surface condition, and pollution.
Dimensional Deviation: Measures length, width, and thickness.
Physical and Mechanical Properties: Tests tensile strength, elongation, compression set rate, rebound rate, tear strength, indentation performance, and moisture absorption rate.
Combustion Performance: Evaluates flame retardant grade, oxygen index, vertical and horizontal burning tests, smoke density, and corner burning test.

Sponge Falling Ball Rebound Tester
This device is specifically designed to measure the rebound rate of flexible polyurethane foam. Key features include:

Measurement Process: A steel ball of specific quality and diameter falls from a fixed height onto the foam sample. The rebound height is measured to calculate the rebound rate.
Control and Display: Operated by a microprocessor with a Chinese LCD display, capable of printing test data.
Design and Structure: Made from silver-gray painted steel and APS aluminum alloy, fixed with stainless steel screws, offering a sleek appearance.
Data Capture: Features a ring-shaped anti-jamming device for high data capture accuracy (96%).
Standards Compliance: Supports both national (460mm) and American (500mm) rebound coefficients with manual switching.
Automatic Correction: Automatically corrects errors to ensure data accuracy.
Ease of Use: Utilizes TST intelligent control system with a simple Chinese menu, offering easy operation, abnormal alarms, minimal maintenance, and one-key data printing.
Level Adjustment: Equipped with a spirit level for horizontal positioning, adjustable via foot pads.

Sponge foam falling ball rebound tester With the improvement of living standards, consumers have higher requirements for purchasing household products, and the industry standards are also getting higher and higher. In addition, the epidemic has also prompted environmental protection and health to become the main theme. Flexible polyurethane foam has good softness, high resilience, can be bent and cut arbitrarily, light weight and good chemical stability, so flexible polyurethane foam is usually used as a thermal insulation material and a buffer material. It is used in furniture, car seats, sofas, mattresses, etc. Test items for flexible polyurethane foam 1. Appearance quality inspection items: color, pores, cracks, surface on both sides, pollution 2. Dimensional deviation measurement items: length, width, thickness 3. Physical and mechanical properties testing items: tensile strength, elongation, 75% compression set rate, rebound rate, tear strength, indentation performance, moisture absorption rate 4. Combustion performance testing items: flame retardant grade, oxygen index measurement, vertical burning test, horizontal burning test, smoke density grade, and corner burning test.

For the rebound rate of flexible polyurethane foam, our company has specially developed a simple equipment--sponge falling ball rebound tester. The product performance is as follows: 1. The sponge falling ball rebound tester has a steel ball of a certain quality and diameter, which falls from a fixed height to the surface of the sample, measures the height of the steel ball bouncing, and calculates the percentage of the ratio of the steel ball bouncing height to the falling height. 2. The sponge falling ball rebound tester is controlled by a microprocessor, and the liquid crystal display is displayed...

6. Dual-standard switching The sponge falling ball rebound tester meets both the national standard 460mm rebound coefficient and the American standard 500mm rebound coefficient, and the manual sliding switching device can freely switch between the two standards. 7. Automatic correction function In the case of errors in the sponge falling ball rebound tester, the microcomputer automatically corrects the errors to ensure the accuracy of the test data. 8. Simple operation The sponge ball rebound tester adopts TST intelligent control system and Chinese menu, which has the advantages of simple operation,...
