Common Questions About EPP

Block-EPP

1. Why does EPP need to be stored under

pressure before use? Will this part restrict

production and become a bottleneck?

The pressing process is mainly the pretreatment

of raw materials. The pressure-holding process

increases the internal pressure of EPP particles

and facilitates better adhesion between the

particles during subsequent foaming. The pressing

process does not limit production and becomes a

bottleneck. Usually two factories will set Tanks to

meet capacity needs.

2. Do EPP foams need catalysts and other

auxiliary materials?

EPP is a physical foam. Unlike the chemical foam

of polyurethane foam, it does not require a

catalyst, and only needs to send heat source steam

to the mold cavity to foam. This is also a factor

of its non-toxicity and odor.

3. What is the main energy consumed by

EPP equipment and is it electrical energy?

The main energy source of EPP is water vapor.

If water vapor is generated by electricity, the

main energy consumption is electricity. But

usually because of cost considerations, most of

them will use renewable energy (such as straw),

followed by natural gas, and finally consider

electricity.

4. Water vapor is needed for EPP foaming,

so is the water consumption large?

The water consumption is not large, because the

water condensed by water vapor can be recycled

and reused, and the water vapor that has dropped

in temperature will be returned to the boiler

through the pipeline.
