Products Description
Rubber Products : It is widely used in industry , agriculture , national defense , transportation , transportation , machinery manufacturing , medicine and health fields and daily life , such as tires used in transportation ; transportation belts , transmission belts , various sealing rings for industrial use ; medical gloves and blood vessels ; rubber shoes , raincoats , warm water bags used in daily life are all made of rubber as the main raw material . Aircraft , cannons , tanks used in national defense, and even rockets , artificial satellites , spacecraft , spacecraft , space shuttles , etc. used in the field of cutting - edge science and technology , require a large number of rubber parts .
Rubber diaphragms have a wide range of applications, but are most often used in environments where pressure differentials are present. With low fluid permeability and the ability to flex from side to side, rubber diaphragms act as a sealing solution while providing a consistent pressure differential.
Elastomers, and rubber in particular, are a great material to use for diaphragms due to their elastic properties. Rubber diaphragms allow for a wide range of pressure differentials while remaining durable and flexible.
Rubber diaphragms are commonly made with rubber materials like
Diaphragms made only of rubber are called homogeneous rubber diaphragms. In this case, the diaphragms are typically compression molded because they’re so thin. It’s difficult to make a thin, flexible membrane through injection molding or transfer molding.

Name | Photo | Authority |
NSF | ![]() |
NSF is specialized in standard setting, product testing and certification services in the fields of public health, safety and environmental protection, and is an authoritative body in the field of public health and safety |
KTW | ![]() |
The supplier is required to comply with DVGW (German Gas and Water Association) Regulation W 270 "Propagation of microorganisms on Non-metallic materials". This standard mainly protects drinking water from contamination with biological impurities. All drinking water systems and excipients exported to Europe must be KTW certified. Therefore, if Chinese drinking water systems and excipients are to be exported to European countries, they must pass KTW certification. KTW has been authorized by the World Health Organization (WHO) for the certification of safe drinking water. |
WRAS | ![]() |
WRAS(Water Regulations Advisory Scheme) certification refers to the Water Regulation Advisory Scheme. WRAS is the certification of the safety of drinking Water in the UK. |
UL | ![]() |
Founded in 1894, UL has become one of the world's leading testing and certification organizations with a complete set of management systems, standard development and product certification procedures. |
SGS | ![]() |
SGS certification refers to the service that SGS performs compliance certification on targets according to standards, regulations, customer requirements and other conditions. To carry out relevant certification, we must pass inspection, testing, authentication, certification and other means (SGS certification itself is not a certification, but refers to the certification service of SGS). |
