PE vs Aramid: Who gives you the best ballistic protection?
When talking about bulletproof products, common materials include polyethylene (PE) and aramid (Aramid). There are some obvious differences in the use of these two materials in bulletproof products:
Material composition:
PE (polyethylene): PE is a synthetic plastic, usually high-density polyethylene (HDPE) or ultra-high molecular weight polyethylene (UHMWPE). PE is usually used in bulletproof products in the form of rigid plates, such as bulletproof plates or bulletproof shields.
Aramid: Aramid is a synthetic fiber, the most common types of which are Kevlar® and Twaron®. It is usually used in fiber form to make bulletproof materials, such as bulletproof cloth, bulletproof panels, bulletproof helmets, etc.
Strength and weight:
PE is generally lighter than aramid but can provide higher ballistic resistance at the same thickness. This makes products made of PE materials more competitive in situations where lightweight performance is required.
Aramid is somewhat lighter, but generally requires thicker material to provide the same ballistic properties. Therefore, products made of aramid may be heavier.
Bulletproof performance:
PE performs well in ballistic resistance and usually has high ballistic resistance and can withstand the impact of high-speed bullets or shrapnel.
Aramid materials also provide good ballistic properties, but generally require more layers or thickness to compete with PE.
Durability:
PE usually provides better ballistic resistance in the short term, but may gradually degrade over time when used over time or when exposed to environmental factors such as UV exposure.
Aramid materials are generally more resistant to environmental factors and more durable.
Price:
Generally speaking, PE material is relatively cheap because its production process is relatively simple.
Aramid is generally more expensive because its preparation process is more complex and it has certain special properties.
The choice of which material to use depends on the specific application needs. If lightweight and high performance are required, PE may be a better choice. If a more durable product is required, aramid may be more suitable. No matter which material you choose, you need to make the most appropriate choice based on the design and purpose of the product. In addition, the manufacturing and quality control of bulletproof products are also crucial to ensure their performance and safety.
