Test of hard and soft foam

Elastic porous foamThe main purpose is to provide comfort.It is good performance damping and isolation performance.Project of polyurethane foam used in mattresses, furniture and car seats, the application of heat insulation and sound insulation, and other requirements.Elastic porous foam的其他应用包括过滤器、包装、密封件和海绵，其他的诸如聚乙烯的聚合物也用于这些应用。

Mostly in the test methodISO standardsandASTM D3574Are defined.

Rigid foamUsed for heat insulation in buildings and refrigeration, used to isolate the impact of sound in the house, in the plane and the wind turbine is used as the core material of sandwich structure and sandwich composites, or in the shop in decorating, used as a lightweight hard material with coating.

It is also used in packaging technology.This type of foam is a kind of expanded foam, foaming polymer.Using polyurethane (PU), polystyrene (EPS), polyvinyl chloride (PVC), polypropylene (EPP) and phenolic resin (PF) made of rigid foam has a wide range of applications.Foam is made into obturator or opening, or containing solid surface and honeycomb core of the whole piece of foam.

For these materials, the test method is based on the standard in the field of application.The determination of thermal properties and fire prevention performance is very important.Compression and shear test is the main mechanics experiment method, the tensile properties is also very important.

Used for testing the material mechanical properties of important test standards include:

• ISO 844 - compression performance measurement
• ISO 1922 - determination of shear strength
• ISO 1926 - determination of tensile properties
• EN 1607 - determination of tensile strength on the surface of the perpendicular to the heat insulation products
• ISO 1209-1 - general bending test
• ISO 1209-2 - bending strength and bending elastic modulus measurement surface
• ISO 7616 - under certain load and temperature compression creep under the condition of determination

ZwickRoell inThe test of elastic porous foam and rigid foam plasticDomain is a global leader.ourCLine C type frame material testing machineIdeal is big bubble test sample.Small usually use standard test specimenUniversal material testing machineFor testing.We used for porous foam material testTestXpert softwareComply with all measuring compression stress value, indentation hardness and compression performance, tensile strength and tear growth performance requirements.Test program is based on individual standard defined in advance.This means that you can be sure of your trial order is correct, and obtain accurate results.

Provides a special ZwickRoellElectronic dynamic fatigue testing machineUsed forHigh cycle fatigue test.The machine specially designed for high speed test and rapid change direction, is to perform the standard ideal for high cycle fatigue test.However, the tester can also be used for static test, measurement, such as the compression stress value, indentation hardness and thickness and hardness of the characteristic value.

Moreover, ZwickRoell offer sample preparation, bulk density measurement, resilience and shore hardness of the equipment.
