It is considered a low hazard plastic with a low risk of leaching. No. 2 plastic is the most commonly recycled plastic, and recycling plastic for recycling is a relatively simple and cost-effective method. This type of plastic is very wear-resistant and will not break down in direct sunlight or extreme heat or freezing.
It is used to make picnic tables, plastic planks, park benches, litter boxes, bedspreads for trucks and other products that require weather resistance and durability. Products made from HDPE are reusable and recyclable, such as the rigid plastic used to make milk jugs, detergent and oil bottles, children's toys, and some plastic bags.
Some studies have shown that it can leach the endocrine disruptor nonylphenol (added to HDPE as a stabilizer), especially when exposed to UV light (such as sunlight) and other possible stabilizer chemicals with estrogen-mimicking activity.
