Performance Importance & Functional Influence of Car Sun Shade Materials

Car sun shade material decides its overall performance and use value. Different materials have big differences in heat insulation and UV protection. They directly affect the car internal temperature and sun protection effect.

At the same time, material choice greatly influences durability. It decides the service life and anti-aging ability of the sun shade, and it also affects folding performance, making it easy to store and carry daily.

Besides, material decides the printing quality of patterns, and improves the look and texture of the sun shades. In addition, raw material is a key point to control production cost. It further affects car sun shades price, profit and market competitiveness.

Material Qualities for Car Sun Shades

• Aluminum Foil

It includes regular aluminum foil, bubble aluminum foil, thickened aluminum foil, single sided and double sided aluminum foil. The surface is covered with pure aluminum foil for silver reflective effect. It has two structures: no middle layer or bubble middle layer. The material is firm, keeps shape well, and is widely used for car front windshield sunshades.

Advantages:

1. High reflection, blocks sunlight and heat, cools the car fast.
2.  Blocks UV rays well, protects car interior from aging and cracking.
3. Low cost, easy production, good for large quantity order.
4. Waterproof and dirt-resistant, easy to clean.
5. Bubble layer design brings better heat insulation than normal foil.

Disadvantages: 

1. Hard material. Easy to fold with marks, crack and peel off powder after long use.
2. It’s easy to turn dark after long sun exposure, lose shine.
3. Easy to get hard and brittle in cold weather, short service life in low temperature.

• PE Foam

PE Foam includes normal PE foam, EPE pearl cotton and composite foam. And it is a soft white foam material. It is mostly used as the middle layer of sunshade. Its surface can be bonded with aluminum foil or silver coated fabric. It is soft and elastic, with thickness from 2mm to 5mm for choice.

Advantages:

1. Softer than pure aluminum foil, not easy to break after folding.
2. Foam layer with air inside, good heat insulation.
3. Light weight, easy to roll up and store, save car space.
4. Good toughness, not easy to deform, supports sunshade shape well.
5. Moderate cost, cheaper than bubble foil, better heat insulation than pure fabric.

Disadvantages:

1. Not high temperature resistant. Easy to turn yellow, shrink and age under strong sun.
2. Low quality foam may have a slight plastic smell.
3. Cannot be used alone, must laminate with foil or fabric.
4. Poor water resistance, hard to recover after getting wet.

• Polyester

Polyester is the most common base fabric on the market. It has many densities such as low elastic, high elastic and high density. It can be made with single side silver coating, double side silver coating and black glue coating.

Advantages:

1. Wear and tear resistant, not easy to deform after repeated folding.
2. Anti-aging and corrosion resistant, long service life under sun.
3. Washable and easy to clean.
4. Support printing, edge wrapping and custom logo.

Disadvantages:

1. Pure polyester without coating has no heat insulation, only for light shading.
2. High density fabric costs more than aluminum foil and PE foam.
3. Thick Oxford cloth is heavy, takes more storage space.

• Nylon

This category includes waterproof nylon cloth and high elastic nylon fabric. Its fiber texture is finer than polyester. The cloth surface feels smooth and gentle, and owns a higher grade than ordinary polyester fabric.

Advantages:

1. Strong toughness, better tear resistance than polyester.
2. Good water repellent, durable for outdoor use.
3. Soft premium feeling, no cheap plastic texture.
4. Not easy to wrinkle, keeps the sunshade flat and nice shape.
5. Stable performance, not easy to harden in cold weather.

Disadvantages:

1. High material cost, higher price, not good for low price bulk order.
2. Easy to be hooked and scratched by sharp objects.
3. Need extra black glue coating for a good shading effect.

• Mesh

This mesh adopts a semi-transparent grid design with tiny holes. The material is light, breathable and keeps a clear view. Most car sun shades are black, which blocks strong light without affecting sight lines.

Advantages:

1. Light and breathable, no stuffy feeling inside the car in summer.
2. Semi-transparent design, safe for driving and parking.
3. Easy installation with magnetic, suction cup or hook design.

Disadvantages:

1. Almost no heat insulation, only blocking strong light, cannot cool a car.
2. Cannot block hot air, car still gets hot in strong sun.
3. Not fit for the front windshield, only for the side and rear window.
4. Low density mesh has poor shading effect.

How to Choose Car Sun Shade Material

When you choose materials for car sunshades, follow your market position.

If you focus on wholesale and bulk sales, pick aluminum foil. It insulates heat well, costs little, and sells easily in most markets. For mid range retail business, choose PE foam composite material. It feels softer than aluminum foil, does not break easily when folded, and balances price and comfort very well.

If you need printed and custom designs, polyester is a good choice. It is wear-resistant, sun-proof, washable, and easy for different style customization. For high end quality positioning, nylon works best. It is tear-resistant, water-repellent, and has a premium texture. For side window and rear window sunshades that only need shade without blocking sight, mesh is the right option. It is light, easy to install, and will not block the driving view.
