APPLICATIONS

RUBBER MOULDING (PREFABRICATED) :

• Absorbing / safety tiles for playgrounds

• Road building accessories

• Gymnasium flooring

• Vibration dampening mats / items for railroad tracks

• Flexible under layer mats for indoor / outdoor sport flooring

• Construction proofing mats (protection and sound proofing)

IN-situ” RUBBER REBONDING / OUTSIDE SPORT FLOORING:(Certification as per EN 1177 (2008) or ASTM F2373)

•Playground areas

• Bottom layer for athletic tracks

• Top or bottom layer for tennis courts

• Multi-purpose outside facilities

•Gymnasium Flooring

“In-situ” but inside rubber rebonding activity:

•Functional, decorative floor coverings


Outdoor Sports

IAAF certified athletic tracks use Dow binders

Other sports includes like Tennis, Badminton,

Basketball, etc.

Somaiya College, Mumbai

Patiala

Indian Air Force Station, DelhiMCA Recreation Centre, BKCCricket box, Thane

Certification of surfaces as per EN or ASTM standards from

IAAF accredited labs

Pour in Place Technology


The fall height below which a life-threateninghead injury would not be expected to occur.

minimum required surface thickness to prevent injury

• VR:

• Virgin rubber is sustainable

• ultimate design, performance and function

• SBR

• Styrene –butadiene-Rubber (Synthetic rubber copolymer)

• Used in car tires & truck tires

• EPDM

• Ethylene propylene diene Monomer

• Peroxide is used in cross linking

• Used in vibrators, seals, insulation etc application

• TPV

• TPV Elastoprene is a mixture of polypropylene and vulcanized EPDM Rubber

• Recyclable and reusable.

Pour in Place Application


• Top layer Binder (EPDM)

• Resilience

• High performance

• Tensile strength

• Taber resistance

• Bottom layer Binder ( NR)

• Cushion layer

• Fibers or granules

• Challenges :

• On site application

• Specification

• Regulatory requirements

Pour in Place Construction


Pour in Place Technology

Balanced reactivity profile: long open time (good process ability)

whilst providing fast and reliable cure

Fast return-back – to service times

Versatility of the binder towards outside climatic conditions

Less seasonality of the application job

Enhanced green strength and increased elasticity performance

Key Technical Requirements for PU Binder

→→ Fulfill all these requirements with Dow’s Controlled Reactivity

Prepolymers
