Contact allergy to rubber gloves is primarily caused by accelerators added to speed up rubber vulcanization, including carbamates, thiurams, 2-mercaptobenzothiazole (MBT), and 1,3-diphenylguanidine (DPG). It may also be caused by antioxidants that prevent rubber deterioration, such as black rubber mix chemicals ( -phenylenediamines).

The sulfur reversion process in natural rubber in terms of

The polysulfide crosslinks formed by these reactions may contain four to six sulfur atoms at low temperatures whereas at higher reaction temperatures shorter sulfur bridges are formed. Vulcanization of rubber by sulfur alone is extremely slow and can take several hours at elevated temperatures (140°C or more).

Effect of non-oiled sulfur concentration on the adhesion

SULFUR DONARS: Sulphur donors are accelerators that are used in a rubber formulation when improvements in heat aging and compression set are required. They are unique in that they provide either mono or disulfidic bonds to the rubber compound. Unfortunately, the most common sulphur donor, DTDM, is based on morpholine, and just like the

The application of the sulfur donor principle to the single accelerator systems discussed above can be expected to provide the ultimate in heat resistant natural rubber. A successful application based on sulfur-0.4 phr, donor-1.5 phr, and TBBS-4 phr achieves excellent property retention after oven aging of 28 days at 100°C.
