Phthalate is used in plastics, primarily in softer materials found at the lower end of the durometer range. We test for 11 phthalates (DBP, BBP, DEHP, DINP, DNOP, DIDP, DnHP/DHEXP, DIBP, DPENP, DCHP, DIOP), and government regulations require that levels be below 1000 ppm (parts per million).
We do not state that our products are phthalate free, but all of our products are well below government regulations. While some items contain less plastic than others, test machinery has a minimum limit as to how low it can test. Normally any readings below 20 ppm register as "not detectable," meaning that phthalate may be present but not at a detectable level. Particleboard itself does not contain phthalate, but the edge banding is made of PVC and may.
