Sintra is a closed-cell expanded foamed PVC material with a "harder" plastic veneer. Sintra has a high strength to weight ratio with makes it very flexible but won't break upon impact.

The sintra slats are to be used for the top sections of the jumps. If a dog were to hit or clip a jump, using sintra would minimize the harm to the dog.

I supply pre-cut white 3/8" thick sintra slats in 1" and 2" sections. They are white and the edges are slightly beveled.
