Why do some silicone products have a bad smell?

Why do some silicone products have a bad smell?

Some silicone products have an unpleasant odor because manufacturers may use low-quality, inexpensive curing agents to cut costs. These curing agents, which are chemicals that help silicone materials harden, can release volatile organic compounds (VOCs) that cause the smell. 
Unlike our environmentally friendly curing agents that pass rigorous ROHS testing, these lower-quality options can leave behind residual odors.
