Vipal Rubber says it invests in technology and in the development of products that save money while minimising their environmental impact, and the latest Vipal release to arise from this focus is the VT170 ECO. The retreading materials producer reports that this freight haulage tread was recently verified by the SmartWay Transport programme in the USA. To date the Latin American market leader is the only retreading products manufacturer in South America to achieve this validation.
