Description

«Uniplast» is used as a plasticizer that does not contain mineral oils and fire hazardous substances for production of polymer-modification binders in accordance with GOST R 52056-2003 in road construction.

Uniplast – the liquid is dark brown at 25°C, which makes it easy to dose and pump. At temperatures below 15°C, the product thickens, in which case the product must be heated before use.

Issues to solve:

At injection thermoplastic elastomers into bitumen without plasticizers, 5–6 % of polymer by weight is required to obtain PMB with optimum properties. Thereby, the viscosity of the resulting binder is significantly higher than that of bitumen, which can lead to technological difficulties in the process of preparation of asphalt concrete mixes at Asphalt concrete mixing plant. You should not increase the temperature of preparation to more than 160 ° C, because in Russia, oxidized bitumen is used, which is subject to intensive ageing at temperatures above 160 ° C. The initial temperature of polymers destruction, such as SBS (styrene-butadiene-styrene), is 180–190 ° C.

“Uniplast” use allows to provide the required temperature conditions (not exceeding 160°C) and significantly improve efficiency of the injected polymer, i. e., to receive PMB with developed three-dimensional structural polymer network at a minimum content of the polymer of 2.0–2.5 %, as well as, in some cases, exclude colloidal mill from the required equipment set.

Main Advantages

Package and Storage

The preparation is delivered in metal barrels with a capacity of 216 l or 52 l and polymeric containers with a capacity of 1 m³.
The preparation is stored in transport package or in tightly closed and sealed packing containers. The preparation is stored in closed storage areas at a distance of at least two metres from heating elements at temperatures from minus 35 ° C to plus 50 ° C, in outdoor areas under a canopy, or in specially equipped heated containers.
Warranty storage period is 1 year from the date of manufacture.
