OKRUBBER
OKRubber powders are surface activated well-milled tyre rubber particulates.
These powders has unique set of properties and can be efficiently used in rubber
and polymer blends and alloys as well as in composite materials.
OKRubber is free-flowing tyre rubber powder. OKRubber particle
surface is chemically modified and activated in the course of special processing in oxidative
atmosphere. It is enriched by reactive chemically functional groups such as carbonyl,
carboxyl, hydroxyl and some others.
OKRubber particle bulk material isn't affected by the modification treatment,
and it saves initial tyre rubber properties.
Due to their surface chemical activity OKRubber particles have good wettability
and adhesion with polar liquids and polymers.
Several surface activated tyre rubber powder materials are available in the
marketplace. These market analogues are described and
compared with OKRubber in appropriate site section.
There are a number of OKRubber advantages over these materials:
due to special treatment in ozone atmosphere OKRubber powders have
enhanced chemical potential,
due to unique production technology OKRubber particles are free from
mechanical damages and rubber structural defects, which are inherent in common
mechanically ground crumb rubber,
due to regular particle shape OKRubber powder has higher bulk density
than common rubber powders,
due to economically efficient modification technology OKRubber powders
have lower production costs and - prices.
Heightened chemical potential of OKRubber powders allows to recommend
them as active efficient fillers for some expensive polar polymer and oligomer
materials such as polyurethanes, epoxies, thiokols, polyvinylchlorids, nitrile
and acryl rubbers for production of various composite materials with high technical-economical
properties.
Good OKRubber wettability by polar liquids, and particularly by the water,
allows using them efficiently:
with water emulsion (latexes) for various coatings (heat-, sound-, waterproofing,
anticorrosion),
for foam rubber articles production,
as the sorbent for water cleaning from organic pollutions.
OKRubber applications are described in more details in
Applications Guide page as well as in the pages related
to the particular applications.
