Biomimetics is on everyone’s lips and it is now difficult to imagine a future where it does not play a key role in the development of our society. The development of new materials is not unconcerned with this new discipline, though we must be aware of what we can obtain (and what we cannot) from imitating nature.
Materials for the Carbohydrate Economy
One of the most significant future transformations in the material sphere will be the development of a carbohydrate economy. This will be a global economy based primarily on renewable material feedstocks—as opposed to our current economy, which is founded largely on fossil fuels.
Mystic Vehicle of Contemporary Technology
If you carefully observe designed objects around you, perhaps you may find the unspoken process of their birth. Their ingredients and parts should come from somewhere in this globe, and mixed and combined together in a factory of somewhere, through hands and ideas of somebodies.
Iran, France Sign MoU to Produce Car Rubber Parts in Iran
Iran and France signed a memorandum of understanding on Tuesday to produce automotive rubber parts in Iran in an agreement that is set to turn domestic producers into parts suppliers for French carmakers.
The agreement was signed by Mehdi Nekoumanesh, head of Iran Polymer and Petrochemical Institute (IPPI), and the president of Union des Syndicats des PME du Caoutchouc et de la Plasturgie (UCAPLAST), Denis Vaillant, Shana News reported.
UCAPLAST is an independent employers’ organization which represents all small and medium-size French enterprises in the rubber and plastics industry.
The MoU calls for sharing expertise of UCAPLAST member companies with Iranian manufacturers.
Affiliated to the Ministry of Science, IPPI oversees activities of 20 knowledge-based companies which produce rubber parts for automobiles.
The businesses are expected to sign an auto parts and supplies contract with the French automaker Citroen. The French company already has a joint production deal with Iran’s second-largest automaker SAIPA.
According to the deal, Citroen is required to export 30% of vehicles or auto parts manufactured under the JV through its international sales network.
The IPPI-UCAPLAST arrangement will enable local auto parts suppliers to make products that meet Citroen standards.
The MoU was signed on the sidelines of 11th International Exhibition of Plastics, Rubber, Machinery, and Equipment (Iran Plast 2017) held Sept. 24-27 in Tehran.
Easy Exports
For selling vehicles and components in the EU and countries under the United Nations Economic Commission for Europe Regulation 10, companies must have the E-mark certificates for their products.
However, according to the Head of the Bureau Veritas automotive department in Iran, Mehdi Parvini plastic automotive parts used in vehicles’ interior are exempted and do not need the certificates.
Obtaining E-mark certificates is an arduous and time-consuming exercise and seen as a hurdle to automotive exports from Iran. Therefore, it would be easier for Citroen and other French auto companies operating in Iran — namely Renault and Peugeot — to export plastic automotive parts produced in Iran through their international networks instead of exporting vehicles or engine parts.
Outdated technology used by Iran’s supply chain are seen as a hurdle in the way of expanding the local automotive industries and implementing local carmakers joint venture contracts with foreign firms.
Law stipulates that in all new agreements signed with foreign companies at least 40% of the vehicle parts should be manufactured in Iran. However, foreign carmakers are reluctant to comply for more reasons than one.
The IPPI-UCAPLAST deal should contribute to the implementation of the new JVs with foreign firms because plastic parts have an obvious share in the production of vehicles.

About Closed Cell Sponge Rubber
Closed cell sponge (or foam) is one of the two major categories of sponge material (the other category is open cell sponge). Closed cell sponge is a type of expanded rubber. Closed cell sponge is created when the bubbles produced during the manufacturing process are completely encompassed within the liquid raw material used to make the sponge. When the liquid sets, the gases are entirely encapsulated within each individual bubble, creating a solid yet lightweight structure.
Closed cell sponge is an extremely versatile material from which a variety of products can be fashioned. Because it is particularly good at keeping out moisture and water, closed cell sponge is very effective in applications where a watertight seal is required.
Closed-cell sponge does not have interconnected pores. As a result, closed cell sponge has a higher compressive strength than open cell sponge due to its structure. Closed cell sponge also possesses a higher dimensional stability, low moisture absorption coefficient, and higher strength compared to open cell sponge.
Closed Cell Sponge Applications and Products
At Hebei Shida Seal Group we make a wide range of products from closed cell sponge which service a diverse range of applications and uses. These include parts for automotive vehicle applications and general industrial use. Examples of products and parts that we have produced from closed cell sponge include: isolators, dual extrusions and weather stripping.
Closed cell sponge is an appropriate material to consider for any of the following types of applications:
- Thermal insulation
- Seals and gaskets which protect against the intrusion of moisture, UV light, or dirt
- Joint fillers and edge extrusions
- Packaging
Types of closed cell sponge material which we stock includes the following:

Ethylene Acrylate Rubber (AEM, Vamac® )
Ethylene/Acrylic elastomer (AEM, Vamac®)
Ethylene/ acrylic elastomer is a copolymer of ethylene and methyl acrylate plus a small amount of a curesite monomer containing carboxylic acid groups. AEM is a tough, low-compression-set rubber with excellent resistance to high temperatures, hot mineral oil, fluids and weathering. The low temperature flexibility and mechanic properties are better than ACM, but it is not well resistant to low aniline oil (like ASTM No. 3 oil) and polar solvents. AEM is typically chosen for applications requiring improved performance versus Nitrile rubber, Neoprene or reduced cost versus higher-end elastomers such as HNBR, FKM. It also usually is applied in automotive industry.

Polyurethane
POLYURETHANE (PU)
(Urethane – Polyurethane – Thermoplastic & Thermoset)
Polyurethane is a unique material that offers the elasticity of rubber combined with the toughness and durability of metal. Because urethane is available in a very broad hardness range (eraser-soft to bowling-ball-hard), it allows the engineer to replace rubber, plastic and metal with the ultimate in abrasion resistance and physical cost. Many applications using this ultra-tough material have cut down-time, maintenance time and cost of parts to a fraction of the previous figures.
Urethanes have better abrasion and tear resistance than rubbers, while offering higher load bearing capacity. Compared to plastics, Urethanes offer superior impact resistance, while offering excellent wear properties and elastic memory.
Urethanes have replaced metals in sleeve bearings, wear plates, sprockets, rollers and various other parts, with benefits such as weight reduction, noise abatement and wear improvements being realized.
Applications:
- Belts
- Metal forming pads
- Wear strips
- Bumpers
- Gears
- Bellows
- Machinery mounts
- Cutting Surfaces
- Sound-dampening pads
- Chute and hopper liners
- Prototype machined parts
- Gaskets
- Seals
- Rollers
- Roller covers
- Sandblast curtains
- Diaphragms
