What is Proseven?

Proseven is the global pioneer in the development of earthquake-resistant pads using urethane gel. Proseven is also the specialised manufacturer of earthquake-resistant pads in Japan, handling everything from research and development to manufacturing and marketing. Urethane gel is a new material that adds ultra-strong adhesion and ultra-low elasticity to gel, which has the properties of both solids and liquids.
Proseven earthquake-resistant pads are made in Japan, manufactured entirely in Japan using only Japanese materials.
Proseven earthquake-resistant pads are a vibration damping material with excellent flexibility and adhesion, which gives them excellent shock absorption capacity to follow every tremor (forward and backward, left and right, up and down). They conform to the Japan Quality Assurance Organization’s (JQA) Earthquake-Resistant Equipment Fixing Device Inspection Standard (JQACS1117) and have passed the 1,000-Gal earthquake resistance test (seismic intensity class 7). (Tremors in the Great Hanshin Earthquake reached 818 Gal.)

How to Use Proseven
Earthquake-Resistant Pads

Simply stick them onto the bottom of the item. It’s that easy, and you don’t need any tools. They can be removed without leaving any adhesive, so you can re-position them to get them in the best spot. You can also use them again and again after restoring their adhesive strength by washing off any dirt with water. (If a pad gets oil etc. on it, remove the oil with a neutral household detergent.)

Proseven earthquake-resistant pads are widely used to anchor computers and other machinery as well as furniture in the office, and of course, to protect household furniture and appliances that could easily topple in an unanticipated earthquake or accident in your home.

Proseven Pad
Applications

I Fine art works and cultural treasures

The pads are 5-mm thick after applying them, so they are well hidden and do not spoil the item’s beauty. For that reason, they are used to anchor fine art works and cultural treasures.

II Production lines and research laboratories, etc.

In addition, because there is no need for anchor bolts (hole drilling) there are no worries about dust or fine particle.
Taking advantage of this feature, they have been frequently used in clean rooms, R&D lines, production lines, and so on.

Environmentally Friendly

Proseven Pad – Environmentally
Friendly

Proseven earthquake-resistant pads have passed off-gas (VOC) analysis (they do not give off volatile toxic substances harmful to health). They conform to the Restriction of Hazardous Substances Directive (Green Procurement Standard), they do not give off harmful organic gases, and they contain no lead, hexavalent chromium, mercury, cadmium, etc., which means they are a reassuringly safe, environmentally friendly material. They can be used in a wide temperature range, from -20°C to 75°C. For hygiene safety, they are also antifungal (JIS Z 2911 Fungus Resistance Test).

Objective

Proseven’s Aims

Proseven has developed the only earthquake-resistant pads in Japan from eco-friendly, high-performance biomass. With the environment a key issue, the pads contain plant-derived constituents, making them a safe, reassuring, and environmentally friendly product. Compared to the conventional product Proseven has greatly increased earthquake resistance load to 1.4 kg/cm2 (conventional product is 1 kg/cm2), inhibited degradation, greatly improved product life to about 8 to 10 years (conventional product is 5 to 7 years), and also made them antibacterial as well as antifungal (JIS Z 2801 Antibacterial Performance Test). Having obtained Biomass Mark certification, we are contributing to the prevention of global warming and the reduction of CO2 emissions.
