Furniture Tips You Don't know-About The Resilience of Sponges

HD-F754

The sofa sponge generally uses three kinds of sponges: high elasticity, high elasticity and super soft, and shot. The medium elastic sponge is generally used as the backrest and armrest, and the high elastic and high elastic super soft sponge is used as the seat part, so you can sit down and experience the comfort. Generally, the cushion of the sofa is about 10 cm sunken after the human body sits down.

The high resilience sponge has excellent performance, and the cushion is comfortable to ride. Product performance (such as hardness, color, density, toughness). Physical property: component A and component B are processed into PU high resilience products by one-time molding.

The bubble diameter of high resilience sponge is mixed and distributed, the skeleton is different in thickness, and has a large opening rate. When pressed, it will produce resilience of different supporting forces under different deformation states, so it is called high resilience sponge.

Advantages of high resilience sponge:

1. Good seismic resistance and flexibility;

2. Good tear strength;

3. The hardness is easy to adjust;

4. Excellent resilience and scalability;

5. Foam has excellent remolding ability (it can be restored immediately after being changed, and has good elasticity)

6. It can be made into any shape;

Therefore, the high resilience products made of high resilience sponges can provide better comfort, and are the ideal materials of choice for sofas, cushions and mattresses.

HD-F754 Foamed Plastic Falling Ball Rebound Tester

Product Functions

It is applicable to measuring the falling ball springback performance of flexible polyurethane foam. This instrument freely falls on the foam plastic sample through a steel ball with a given diameter and mass at a specified height, and calculates the percentage of the ratio of the maximum height of the steel ball springback to the falling height of the steel ball, that is, the springback rate, which represents the springback performance of the foam plastic.

Test standard

GB/T 6670-2008, ASTM D3574 (test points TEST H 68 ～ 75), ISO8307-2007, etc

Product features

（1） Hardware characteristics

1. The test of this machine is carried out in a transparent acrylic tube, and the falling process of the steel ball is clearly visible;

2. Equipped with a fast and high-quality micro printer, it can output complete and detailed test data reports.

（2） Software characteristics

The control system adopts the test software independently developed by our company, which can complete all test parameter settings, working state control, data acquisition, analysis and processing, and result display.
