The 5-stage <<EXPANTAY>> is a preformed expansion joint filler we have commercialized to exert composite synergistic effects for all of plastics toughness and beauty, synthetic rubbers (EPDM) durability, unvulcanized butyl rubbers adhesive power, stability in combination with glass fiber, foamed polypropylene elasticity, and stainless steel rigidity.

Not being satisfied with just ISO9001:2008 accreditation, Expantay have gained ISO14001:2004 accreditation. Environmental loads are continuously reduced by Expantay's environmental management system in addition to our quality management and customer-first policy.
Considering Expantay social responsibility as a company and the serious circumstances underlying environmental issues, Expantay has gained ISO14001 accreditation in addition to ISO9001 accreditation.
Enabling a reliable finish, significant improvement in working efficiency, and superior cost performance, the 5-stage EXPANTAY, an ideal combination of the characteristics of 100% closed-cell foam type foamed polypropylene, butyl rubber, synthetic rubber (EPDM), glass fiber, stainless steel, and polyvinyl chloride, is our greatest epoch-making preformed expansion joint filler, surpassing conventional elastite joint fillers.

Construction method (functionality and workability)

 

Simple construction and management, requiring no skills

 

Nonprofessionals can also work and repair with ease.

 

Stable materials with durability not differing from contractors

 

One-shot construction (requiring no primer, installing backup materials at the same time as sealing, and omitting curing as much as possible)

 

Construction is not affected by weather conditions, etc. (all-weather type; and wide working temperature range).

 

Establishment of construction method by which reliable sealing can be performed

 

Easy checking of dimensions and airtightness

Product performance

 

20 - 30 years durable materials (excellent weather resistance)

 

Good adhesion performance (non-retrogressive adhesiveness; and being airtight)

 

Low total cost (cost-effective, and usable in volume)

 

Ease of repair

 

Materials withstanding temperature changes from -30 to 70

 

Performance at on-site construction equal to experimental values

 

Materials capable of every type and durable under stress

 

Changes over time can be seen, and there are no variations between products, which should be reliable.
