SVR3L is produced wholly from field latex. Field latex is preserved with ammoniac or sodium sulfite. The filed latex is coagulated with formic acid, and then make crumbs by passing through a crusher, some crepers and a shredder. After the dried crumbs are cooled and then compressed into blocks and packed in polyethylene bags. SVR3L is a light colored rubber with low dirt content and free of odor.
