Details

Polypropylene (PP)

Polypropylene, abbreviated as PP, is commonly known as fold-resistant plastic.

Classification by Crystallinity

Isotactic PP: Crystallinity is as high as 95% or above, with a molecular weight ranging from 80,000 to 150,000.
Atactic PP: Amorphous at room temperature, with a molecular weight of 3,000 to 10,000, and has limited applications.

Properties and Applications of Polypropylene (PP)

1. Properties of Polypropylene

(1) Physical Properties

a. Non-toxic, odorless, tasteless, presented as translucent or transparent granules (milky white in powder form).

b. Density: 0.90～0.91g/cm³.

c. Water stability: Water absorption rate is only 0.01% after 24 hours of immersion in water.

d. Molecular weight: Ranges from 80,000 to 150,000.

e. Good moldability, high shrinkage rate, and thick-walled products are prone to sink marks.

f. Excellent gloss and easy to color.

(2) Mechanical Properties

a. High crystallinity and regular structure: Higher strength, hardness, and elasticity than HDPE (High-Density Polyethylene).

b. At room and low temperatures: High structural regularity leads to poor impact strength (impact strength increases with the rise of molecular weight).

c. Flexural fatigue resistance: For example, integral living hinges injection-molded from PP can withstand 7×10⁷ times of folding and bending without any damage marks.

d. Dry friction coefficient: Comparable to PA6 (Nylon 6) under dry conditions (inferior to PA6 when lubricated with oil).

(3) Thermal Properties

a. Melting point: 164～170℃.

b. Heat resistance: Can be sterilized at temperatures above 100℃, and will not deform at 150℃ without external force.

c. Brittleness temperature: -35℃ (inferior to polyethylene in cold resistance).

(4) Chemical Stability

a. Chemical resistance: Resistant to most chemical reagents except concentrated sulfuric acid and concentrated nitric acid, which can corrode PP.

b. Softening and swelling: Low-molecular-weight aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, etc., can cause PP to soften and swell.

(Chemical stability improves with the increase of crystallinity, making it suitable for manufacturing various chemical pipes and fittings with excellent corrosion resistance.)

(5) Electrical Properties

a. High-frequency insulation performance: Excellent (almost non-hygroscopic, insulation performance is not affected by humidity).

b. Dielectric constant: 2.0～2.5 (suitable for electrical insulation products used under heating conditions).

c. Dielectric strength: 40KV/mm.

d. Arc resistance: 130s (high static electricity, prone to aging when in contact with copper).

(6) Weather Resistance

a. Photo-aging: PP is sensitive to ultraviolet (UV) rays.

b. Thermal-oxidative aging: Heat and oxygen will accelerate the aging of PP.

2. Applications of Polypropylene

(1) Film Products

PP films are transparent and glossy, with low permeability to water vapor and air, including:

a. Blown films.

b. Cast films (CPP).

c. Biaxially oriented films (BOPP).

(2) Injection-molded Products

Applicable to engineering parts in automotive, electrical, machinery, instrumentation, radio, textile, national defense industries, as well as daily necessities, turnover boxes, medical and health equipment, and building materials.

(3) Extruded Products

Can be processed into pipes, profiles, monofilaments, fishing ropes, packing belts, binding ropes, woven bags, fibers, composite coatings, sheets, plates, etc. Also used for blow-molded hollow products such as various small containers.

(4) Other Applications

Low-foaming products, calcium plastic boards, synthetic wood, laminates, synthetic paper; high-foaming PP can be used as structural foams.

Modification of Isotactic PP (Molecular Weight: 80,000-150,000)

Polypropylene can be modified through filling, reinforcement, blending, copolymerization, and cross-linking.

Adding fillers such as calcium carbonate, talc, and inorganic minerals can improve rigidity, hardness, heat resistance, and dimensional stability.
Adding glass fiber, asbestos fiber, mica, glass beads, etc., can enhance tensile strength, creep resistance, and low-temperature impact resistance.
Adding elastomers and rubber can improve impact performance and transparency.
Adding carbon fiber (CF) can increase strength, especially flexural modulus.
