Tyre Compound A Grade Wigwag is a premium, reclaimed rubber compound composed primarily of top-grade off-spec and excess rubber compounds sourced from original tyre manufacturing processes. This material is known for its consistent quality, excellent processability, and cost-effectiveness, making it a preferred choice for manufacturers seeking a high-performance alternative to virgin compounds.
A Grade Wigwag is meticulously sorted to ensure uniformity in polymer base and filler content. It typically includes a mix of natural rubber (NR), styrene-butadiene rubber (SBR), and butadiene rubber (BR), along with reinforcing carbon black and curing agents. It provides dependable performance in terms of wear resistance, flexibility, and durability, making it highly suitable for various industrial and automotive rubber applications.
This compound serves as an economical and sustainable solution, allowing for significant cost savings without compromising essential performance metrics.

Note: As this is a reclaimed compound, slight variations in physical properties may occur between batches, though all meet A-grade standards.
Uses:
-
Tyre tread and sidewall manufacturing (non-critical parts)
-
Tyre retreading compounds
-
Rubber mats and industrial flooring

Conveyor belts and rubber sheets
-
Automotive components (mud flaps, fenders, splash guards)
-
Footwear soles and midsoles
-
Agricultural tyre components
-
Rubber seals and gaskets
This material is ideal for applications where durability, flexibility, and cost-efficiency are required but where ultra-high performance (like racing tyres) is not the priority.
