Polyester Film Supplied to Indonesia for Electrical Insulation

Project Overview

Xuchang Chengrui Insulation Material Co.,Ltd. supplied polyester film to an electrical insulation materials trading company in Indonesia.

The customer was looking for a more stable source of polyester film for motor insulation, electronic insulation and die-cut insulation parts. Their main concerns were not only price, but also delivery stability, roll quality and consistent technical performance.

After sample confirmation and specification review, the customer placed a trial order with Chengrui. The polyester film was supplied in rolls and prepared with export packing for shipment to Indonesia.

Customer Background

The customer is an Indonesian electrical insulation materials distributor serving local manufacturers and converters.

Their customers mainly use insulation materials for:

• motor insulation parts

• electrical equipment production

• appliance insulation components

• electronic insulation parts

• die-cut insulation sheets

• insulation material lamination

Polyester film is one of their regular products because it is widely used in the electrical insulation industry. It can be supplied directly as PET insulation film or used as a base material for composite insulation products such as DMD insulation paper.

For this customer, stable supply was important. If roll quality or delivery time changed from order to order, it could affect their own customers’ production schedule.

The Challenge

Before working with Chengrui, the customer had several common procurement problems.

1. Unstable Delivery Schedule

The customer needed polyester film for regular supply, but delivery time from previous suppliers was not always predictable.

For a trading company, late shipment can lead to delayed local deliveries and customer complaints.

2. Price Pressure

The Indonesian market is price-sensitive, especially for standard electrical insulation materials.

The customer needed a supplier that could provide stable quality while keeping the cost competitive enough for local resale.

3. Quality Consistency

The customer's clients used polyester film for cutting, slitting, lamination and insulation parts.

This meant they paid close attention to:

• film thickness

• roll surface

• edge condition

• cleanliness

• dielectric performance

• packing condition

Even if the material looked simple, unstable quality could create problems during cutting or final assembly.

Why the Customer Chose Chengrui

The customer found Chengrui while searching for electrical insulation materials suppliers in China.

They were interested in Chengrui because our product range matched their regular demand for motor and electrical insulation materials, including:

polyester film

DMD insulation paper

NMN insulation paper

NHN insulation paper

polyimide film

insulation tape

FR4 / G10 / G11 slot wedges

For this project, polyester film was the first product selected for trial cooperation.

Before confirming the order, Chengrui communicated with the customer about the application, roll size, thickness requirement and packing method. This helped reduce misunderstanding before production and shipment.

Product Supplied

Product Name: Polyester Film / PET Insulation Film

Application: Motor insulation, electrical insulation, electronic insulation and die-cut parts

Supply Form: Roll

Material: Polyester Film

Market: Indonesia

Processing Methods: Slitting, cutting, wrapping, lamination and die-cutting

Polyester film is commonly used in electrical insulation because it offers good dielectric strength, stable mechanical performance and smooth processing.

It is suitable for customers who need a flexible insulation film for regular production or converting.

Technical Points Confirmed Before Shipment

Before arranging the trial order, Chengrui confirmed the key details with the customer.

These included:

required thickness

roll width

roll length

application

dielectric strength requirement

packing method

shipment arrangement

documents required for import

For polyester film buyers, these details are important. The same product name may still refer to different grades, thicknesses or processing requirements.

By confirming these points before shipment, both sides reduced the risk of supplying the wrong material.

Application in Indonesia

After receiving the material, the customer supplied the polyester film to local users for electrical insulation applications.

Typical applications included:

motor slot insulation

phase insulation

insulation spacers

PCB insulation

appliance insulation parts

die-cut insulation sheets

flexible insulation laminates

The material was suitable for customers who needed thin, flexible and stable insulation film for converting or assembly.

For motor-related applications, polyester film can also be used as part of composite insulation materials, especially in DMD insulation paper.

How Chengrui Supported the Customer

This project was not only about shipping polyester film.

The customer also needed technical and purchasing support before placing a repeat order.

Chengrui helped with specification confirmation, product data review, sample support, roll packing suggestions and export packing arrangement

This support was useful because the customer served different end users. Some needed polyester film for simple insulation parts, while others needed more stable dielectric and processing performance.

Why Polyester Film Is Still Widely Used

Polyester film remains one of the most practical electrical insulation films in the market.

It is widely used because it offers:

• good electrical insulation

• stable thickness

• smooth surface

• good mechanical strength

• easy slitting and cutting

• good cost performance

• wide application range

For many motor, electronics and appliance manufacturers, polyester film is not a special material. It is a basic insulation material they need regularly.

That is why stable quality and reliable supply matter more than a one-time low price.

Chengrui's Supply Capability

Xuchang Chengrui Insulation Material Co.,Ltd. supplies polyester film and other electrical insulation materials for motor, transformer and electronic insulation applications.

Chengrui can support customers with roll supply, slit rolls, custom width, thickness confirmation, sample checking, export packing and flexible shipment terms.

Conclusion

This case shows how Chengrui supplied polyester film to an Indonesian electrical insulation materials distributor for motor, electronic and general electrical insulation applications.

For the customer, the key value was not only competitive pricing. They needed stable roll quality, clear specification confirmation and reliable export support.

For customers in Indonesia and other Southeast Asian markets, Chengrui can provide polyester film and related insulation materials according to application, thickness, roll size and processing requirements.
