Pulp molded products

and foamed plastic products are two different types of materials with some significant differences in performance. Here is their performance comparison:

Material properties:

Pulp molded products are typically made from pulp, paper, or other natural cellulosic materials. They may be molded or pressed. These products are relatively strong and have a hard texture.

Foamed plastic products are generally made of polymers (such as polystyrene) that expand to form a foam structure. This makes foam plastic products very light and flexible at the same time.

Weight:

Pulp molded products are generally heavier than expanded plastic products of the same size because the pulp itself is relatively dense.

Foam plastic products are relatively lightweight due to their foam structure.

Mechanical behavior:

Pulp molded products generally have good mechanical strength and hardness and are suitable for some applications that require a relatively strong shell.

The mechanical properties of foamed plastic products are relatively low, but they have certain shock-absorbing and cushioning properties.

Environmental protection:

Pulp molded products are generally more environmentally friendly because pulp is a renewable natural resource and the waste generated during the manufacturing process is relatively easy to dispose of.

The manufacturing of foamed plastic products involves some chemicals, and discarded foamed plastics may cause a certain degree of pollution to the environment.

Applicable fields:

Pulp molded products are often used in packaging, cartons, paper bowls, and other applications that require a relatively strong outer shell.

Foamed plastic products are often used in packaging, thermal insulation, sound absorption and other applications that require lightness and a certain degree of elasticity.

Overall, the choice between pulp molded products and foamed plastic products depends on specific application needs, such as required mechanical properties, weight requirements, environmental considerations, etc.
