Non magnetic, Electric insulation, High strength, E-modulus, Coefficient of thermal expansion near with cement concrete
BFRP Rebar
Product Overview
BFRP is a new kind of composite material, which is Basalt fiber as reinforcement material, combines with vinylite (resin), padding and other curing agent, then through pultrusion molding process.
Product Introduction
BFRP is a new kind of composite material which basalt fiber combines with vinylite, padding and curing agent. The difference with steel, the density of BFRP is 1.9-2.1 g/cm3.
BFRP is a kind of rustless electrical insulator, with non magnetic, especially with great acid resistance and alkali resistance. It could develop the durability of construction.
Property
Non magnetic,
Electric insulation,
High strength, high E-modulus,
Coefficient of thermal expansion near with cement concrete.
High resistance to corrosion, acid, alkali and salt.
Application
Earthquake observing station, Seaport pier protection engineering and construction, metro station, bridge, non magnetic or magnetic concrete construction, prestressed concrete highway, anti-corrosion chemical industry, Chemical storage tank, underground engineering, Mri (magnetic resonance imaging) facilities basis, Communication building, Electronic equipment factory, Fusion buildings, concrete guide board of Maglev railway, Telecommunications transmission tower, Television stents and strengthen core of Optical fiber cable
